Published: April 2024

This study aims to analyze whether Islamic insurance can influence Halal Value Chain planning in Indonesia. This study combines qualitative methods and descriptive statistics by interviewing 10 practitioners and academics regarding how Islamic insurance can build a halal value chain. Then the results of the interview will be processed using the NVivo-12 software. According to the findings, practically every halal value chain cluster, including those in the food and beverage industry, halal tourism, fashion, cosmetics, and leisure media, needs sharia insurance to grow. This is so that, in the event of an unfathomable loss, Sharia insurance can ensure the continuation of Sharia-based businesses. To expand Indonesia's halal business internationally, a Sharia insurance development strategy must be created. The Penta Helix collaboration, which links academia, government, communities, business people, and the media, is one of these initiatives.

Critical Discourse Analysis (CDA) is used in this study to investigate the various constraints faced by female journalists and media workers. This research paper investigates the consequences of limited information access, as well as widespread arrests and intimidation by both government officials and fighters. The study also looks into the Taliban's strict limitations on media activities, such as the division of workspaces, the requirement for women to cover their faces while on screen, and the regulation of analyst involvement in political programming. The intricate power dynamics that underpin their narratives are revealed through this analysis. The de facto government and combatants are portrayed as entities attempting to maintain their authority, whereas the Taliban attempts to impose regressive ideologies to women who work in news media.
Mapping Cases and Actors in Violations of Religious Freedom in Contemporary Madura
Authors: Abd Hannan  , Mursyidi Ach. Fatayillah
Published: April 2024

This study examines the dynamics of violations of the freedom of religion in Madura, mapping cases, actors, and handling models. This study is field research that uses qualitative research with a phenomenological approach. Methodologically, the choice of the qualitative type is based on the research objectives that want to describe the research problem in depth and focus. The research problem is to examine the dynamics of violations of freedom of religion in Madura, mapping cases, actors, and handling models of religious sociology. After analyzing the field data based on the perspective of the sociology of religion, this study found that cases of violations of freedom of religion in Madura tend to occur in the internal scope of the Muslim community, which is generally triggered by the attitude of 'resistance' to the dimensions of freedom of religion or belief, both dimensions of forum internum and forum externum. Based on these actors, the practice of violating the freedom of religion in Madura often involves religious figures. In this context, kyai is the most influential figure as well as the highest religious authority in Madura. In addition, other actors also come from mass organizations or religious groups, which in fact have great power and influence to mobilize the masses, as in the violation of freedom of religion that befell Shia Sampang adherents and Wahabi Muslims in Pamekasan. Regarding handling, the model of handling violations of freedom of religion in Madura has so far been more exclusive. The settlement process tends to produce unbalanced decisions, often centered and in favor of the majority group or groups, especially the local elite circle such as Kyai. In many cases, the handling process is not fully aimed at building a truly accommodative and moderate agreement, but rather at maintaining the status quo, creating domination, intimidation, and even religious intervention against minority groups.
Reception of the Integration of Islam and Science: A Case Study at Islamic Institute of Kediri
Authors: Alamin Taufik , Mujib Abdul , Sulaeman Mubaidi , Nasution Alhafidh
Published: April 2024

The enduring dichotomy between religion and science rooted in historical conflicts during the heyday of Islam and the Western Renaissance has persistently challenged efforts to reconcile the two. In Indonesia, thinkers within State Islamic Higher Education (PTKIN) have proposed the integration-interconnection perspective to bridge this gap. However, after almost two decades, this approach has remained unfamiliar to PTKIN students, including those at Kediri State Institute of Islam. This study aims to assess the reception of PTKIN academics, particularly students from the Faculty of Ushuluddin and Da'wah at Kediri State Institute of Islam, towards the integration of Islam and science, from a Quranic perspective. Conducted as a field research, this study employs a mixed-method approach that combines both quantitative and qualitative methods. This methodological choice sought to provide a more comprehensive understanding of the phenomenon under investigation. This study focuses on the academic community of Kediri State Institute of Islam. The findings reveal that the majority of students in the Faculty of Ushuluddin and Da'wah at Kediri State Institute of Islam perceived a limited correlation between Islam and science. Their understanding diverges significantly from the intended goals of Islam and science integration at Kediri State Institute of Islam. The Islam and Science course offered by the faculty has emerged as a valuable platform for academics and da'wah activists to communicate the concept of integrating Islam and science to their students and broader community. Emphasizing the need for innovative learning modules related to Islam and Science, this study suggests that this approach can facilitate a deeper appreciation of the interconnection integration among PTKIN students. Ultimately, these efforts aim to overcome the persistent dichotomy between religion and science.

Published: April 2024

The internal combustion engine is one of the main factors contributing to the largest exhaust emissions today. So that the engine produces optimal energy, the right fuel is needed to reduce exhaust emissions. Bioethanol is considered to optimize the combustion reaction in the form of CO and HC produced, but bioethanol contains less energy compared to gasoline. An experimental study was conducted directly on the performance and waste emissions of a four-stroke, 1-cylinder internal combustion engine. The purpose of this study was to analyze shell v-power RON 95 fuel blended with 15% bioethanol fuel with carburetor venturi hole size ratios of 26 and 28. With the addition of bioethanol, at venturi 26 and 28, the average torque increased by 20%, while the power at venturi 26 increased by an average of 13%, and at venturi 28, it increased by 7.8%. In terms of exhaust emissions, the use of venturi 26 decreased CO levels by 30.3% and HC levels by 36.6%, while the carburetor with venturi 28 decreased 18.4% and HC levels by 50.3%.

Satellite Nucleoli in the Megakaryocytic Lineage of Rats
Authors: Janoutová J , Likovský Z , Smetana K
Published: April 2024

The present study was undertaken to provide more information on the incidence of satellite nucleoli in developmental stages of the megakaryocytic lineage. Satellite nucleoli representing solitary silver stained nucleolus organizer regions (AgNORs) present in nuclei in addition to other nucleolar types were observed in all stages of megakaryocytic development. However, the incidence of satellite nucleoli was more frequent in mature megakaryocytes than in less differentiated immature megakaryoblasts and naked megakaryocytic nuclei representing the terminal stages of megakaryocytic development after loss of the cytoplasm transformed to thrombocytes. There is a possibility that the increased incidence of satellite nucleoli in mature megakaryocytes might be due to the loss of AgNORs from active nucleoli characteristic for immature cells. The decreased incidence of satellite nucleoli in naked megakaryocytic nuclei might reflect their disintegration in the terminal stages of the megakaryocytic development.

The review aims to describe the effect of thyroid diseases on fertility. There are many causes of infertility in couples and thyroid dysfunction is a critical cause. Thyroid hormones and the hypothalamic-pituitary-ovarian axis interact in several ways and thyroid hormones may modulate ovarian functions. Hypothyroidism causes ovulatory dysfunction and luteal hypoplasia due to decreased progesterone production. Levothyroxine supplementation restores the ovulatory function and ultimately resolves the fertility issues. Regarding the elevated concentrations of antithyroid antibodies in infertile women, high concentrations are associated with a three- to four-fold increased risk of recurrent miscarriages. Moreover, women with positive antithyroid antibodies tend to develop thyroiditis postpartum. In assisted reproduction cycles the presence of antithyroid antibodies is correlated with poorer embryo quality, lower fertilization rates and increased risk of spontaneous abortion. Lastly, hyperthyroid women, especially with thyrotoxicosis, have menstrual disorders such as oligomenorrhea and polymenorrhea. In hyperthyroid women the incidence of infertility is higher.

Published: April 2024

Background and Objectives: Intrauterine growth restriction (IUGR) is worldwide a public health problem. IUGR-born individuals acquire epigenetic “thrifty-phenotype” gene adaptations, according to the “Barker hypothesis” and are more susceptible to develop metabolic related diseases. Small for Gestational Age (SGA) fetuses consist of a transitional group between IUGR and normally grown fetuses (Appropriate for Gestational Age, AGA). Currently, there is limited information in the literature whether IUGR or SGA status affects the pluripotency of the Umbilical Cord Mesenchymal Stem Cell (UC-MSC) with respect to gene expression at various stages of cell culture. Materials and Methods: In this study, we investigated stemness marker expression in UC-MSCs derived from twenty-one AGA, IUGR, and SGA fetuses. The relative expression of key genes involved in stemness, pluripotency, and cell proliferation, namely IGF2BP1, CMYC, GLI1, P21, NANOG, OCT4, and SOX2, was assessed in UC-MSCs at passages P0 and P1 using flow cytometry and quantitative PCR. Results: We found lower median expression levels of IGF2BP1 in IUGR group (P=0.044) and P21 in SGA group (P=0.024) at P0 compared to control group. GLI1 and OCT4 exhibited reduced expression at P1 in the IUGR group (P=0.0434 and P=0.0343 respectively) compared to AGA. NANOG median expression differed statistically between CONTROL and IUGR group in P0 (P=0.034) and P1 (P=0.0205). No significant changes were noted for SOX2 and CMYC median expression among the various groups in P0 and P1. Conclusion: The comparative analysis of stemness marker expression among UC-MSCs from these three different sources is a novel descriptive aspect of our study, adding a new perspective to the existing literature.
Researching opportunities to improve efficiency detection of unmanned aerial vehicles
Authors: Volochiy Bohdan , Onyshchenko Volodymyr , Ozirkovskyi Leonid , Khahula Vasyl
Published: April 2024

The article considers options for the formation of radio electronic systems for detecting UAVs using radar, optoelectronic, thermal imaging and acoustic systems with specified values of performance indicators in their autonomous use. The results of comparing the effectiveness of eight variants of the formation of electronic systems for detecting UAVs of the Lancet, Shahed-136, and Cube types are shown. In these variants, two electronic complexes are considered, which provide for the combination of 3 systems, and 6 electronic complexes, which provide for the combination of two systems. To evaluate the effectiveness of the radio electronic complex for detecting unmanned aerial vehicles of each type, the indicator "probability of UAV detection" is used. The fact of UAV detection is recorded in three variants of partial task completion. The first embodiment of the partial solution of the task takes into account unmanned aerial vehicles detected by three systems.  The second embodiment of the task takes into account unmanned aerial vehicles detected by any two of the three systems. The third variant of the partial solution of the task takes into account unmanned aerial vehicles detected by any one system out of three. To determine the performance indicator, a discrete-continuous stochastic model of the operational functional behavior of an electronic complex consisting of radar, optoelectronic or thermal imaging and acoustic systems with a given algorithm for its functioning is proposed. The development of a probabilistic graph of states and transitions is shown, on the basis of which a stochastic model of the operational functional behavior of the UAV detection electronic complex is formed in the form of a system of Kolmogorov-Chopman differential equations. The degree of adequacy of the proposed discrete-continuous stochastic model of the operational functional behavior of the electronic complex is determined by taking into account the performance indicators of the systems that are part of it. As indicators of system efficiency, we used "the probability of detecting a UAV by the system of the electronic complex when the UAV is in the area controlled by this system" and "the average values of the time intervals from the moment of UAV appearance in the controlled area until the moment of its detection by the corresponding system". To evaluate the increase in the efficiency of the created UAV detection electronic systems, an indicator is used in the form of the ratio of the probability of non-detection of UAVs by one system when it is used autonomously and the probability of non-detection of UAVs by the created electronic system.

Published: April 2024

Today, the effectiveness of the troop and weapons management system has become as much a factor in winning a battle as their quantity and quality. In modern conditions, the management of troops and weapons is almost entirely based on the use of various radio-electronic means, which in turn made it possible to increase the effectiveness of fire damage to the forces and means of the opposing side and significantly improve the quality of the management of troops.

Since radio emission detection and analysis systems receive information from existing electromagnetic fields, receiving antennas are one of their main devices. It is obvious that the improvement of such characteristics of antennas as the efficiency of their deployment on the ground and folding into the transport position, the range of operating frequencies, the amplification factor, the accuracy of measurement, the maximum coefficient of directional action, reliability and ease of maintenance are modern trends in the development of mobile military systems for the detection and analysis of radio emissions from the enemy's radio-electronic means.

According to the results of the review of scientific publications and the study of modern problems of the development of radio monitoring antenna systems, it was established that in recent years the issue of developing mobile broadband antennas - able to be deployed/collapsed on the ground and brought into working position in short periods of time - has become especially relevant. Therefore, it is urgent to find ways to develop the design features of broadband antennas to increase their efficiency (mobility) of deployment/collapse on the terrain. The purpose and main content of the article is to increase the efficiency (reduction of time) of deployment on the ground and folding into the transport position of the logoperiodic vibrating antenna for working with broadband signals in the frequency range of 40–500 MHz.

According to the results of a comparative analysis of the quantitative and qualitative indicators of the developed mobile logoperiodic antenna with its closest analogues, it was established that the developed design of the mobile logoperiodic antenna made it possible to increase the range of operating frequencies of the antenna for the lower part of the VHF range and increase the efficiency of deploying/collapsing the antenna (expanding/collapsing time is reduced 2 times) while the weight and dimensions of the antenna remained unchanged (dimensions of the antenna in the transport position – 2010x600 mm, antenna weight – 7 kg).
Improved method of assessing the combat capabilities of the artillery of the mechanism brigade

Published: April 2024

The experience of repelling and deterring the armed aggression of the Russian Federation indicates the need to carry out a significant amount of joint fire support tasks for combined military units and units. This, in turn, indicates the growing requirements for the implementation of the combat capabilities of artillery units to perform the volume of fire support tasks in the battle of the mechanized brigade.
The conducted analysis of the conduct of artillery combat operations in the battle of the mechanized brigade indicates that the tasks associated with the need to increase the level of realization of the potential combat capabilities of the artillery and bring them into line with the volume of fire missions that can rely on it are problematic and relevant today in the battle of the mechanized brigade.
In order to solve these tasks, there is an urgent need to use modern approaches to assessing the combat capabilities of artillery units, which would take into account the changes that have occurred in the tactics of actions, the spatial and temporal parameters of the conduct of artillery combat operations, the effects of damage and allow better planning of fire support by artillery in battle mechanized brigade. According to these requirements, the assessment of the combat capabilities of artillery should become an important component of planning the combined fire support in the battle of the mechanized brigade.
Therefore, there is an urgent task regarding the improvement of the methodology for assessing the combat capabilities of the artillery of a mechanized brigade, the use of which will make it possible to bring the combat load of artillery units into compliance with the volume of firing tasks of artillery in the battle of a mechanized brigade, taking into account modern requirements, conditions and time constraints for their execution.
The improved method of assessing the combat capabilities of the artillery of the mechanized brigade, unlike the existing methods and approaches, takes into account such a set of conditions and factors that allow predicting the effectiveness of the tasks of artillery units of different purposes and properties (differently effective fire means). To take into account the combined effect of fire, reconnaissance, maneuver, support and management and communication capabilities of artillery units based on the number of combat cycles of their actions. It is expedient to calculate the possibilities for carrying out a certain amount of firing tasks with the allocated resource of ammunition of various types under established spatial and temporal time limits and probable enemy countermeasures.
Based on the results of the comparison of the defined volume of fire tasks and the number of combat cycles, it is possible to make a final calculation of the possible combat load of each artillery unit from fire support per day of battle during the planning of fire support by artillery in the battle of a mechanized brigade.

Published: April 2024

Introduction: Implantable medical devices continue to be vulnerable to bacterial infections. The unrelenting formation of antibiotic resistant bacterial strains not only exacerbates these infections but also renders the current treatment strategies impotent. The need is greater than ever for innovative and effective approaches to counteract drug-resistant bacteria. This study examines the innate antibacterial properties of TiO2 nanotube arrays (TNAs) and their ability to locally deliver antibiotics to inactivate gram-positive and gram-negative bacteria, in vitro.

Methods: Using a two-step electrochemical anodization process, TNAs with a diameter of ∼100 nm and a length of ∼5 µm were grown on titanium substrates.

Results and Discussion: After 24 h of incubation, as-fabricated TNAs showed 100% clearance of Escherichia coli, and 97% clearance of Staphylococcus aureus growth. The antibiotic-loaded TNAs demonstrated sustained slow-release of cefotaxime and imipenem measured over 14 days. In vitro bacterial studies revealed the capability of cefotaxime- and imipenem-loaded TNAs in completely inhibiting the growth with 100% clearance of Klebsiella pneumoniae after 24 and 48 h of incubation. Bacterial inhibition assay revealed a significantly enlarged inhibition zone difference of 18 mm around the imipenem-loaded TNAs against K. pneumoniae compared to the as-fabricated TNAs which was maintained for 7 days with ∼10 μgmL−1 of antibiotic released from the TNAs which was found to be lower than the dose required to completely eradicate multidrug resistant bacteria when used in conjunction with the antibacterial TNAs. The results of our study highlight the potential of TNAs as a versatile platform for addressing treatment strategies related to bacterial infections and antibiotic resistance in implantable medical devices.
Recent advances in ternary Z-scheme photocatalysis on graphitic carbon nitride based photocatalysts
Authors: Zhou Dantong , Li Dongxiang , Chen Zhi
Published: April 2024

Due to its excellent photocatalytic performance over the last few years, graphitic-like carbon nitride (g-C3N4) has garnered considerable notice as a photocatalyst. Nevertheless, several limitations, including small surface area, the rates at which photo-generated electrons and holes recombine are swift, and the inefficient separation and transport of photoexcited carriers continue to impede its solar energy utilization. To overcome those limitations in single-component g-C3N4, constructing a heterogeneous photocatalytic system has emerged as an effective way. Among the various studies involving the incorporation of hetero composite materials to design heterojunctions, among the most promising approaches is to assemble a Z-scheme photocatalytic configuration. The Z-scheme configuration is essential because it facilitates efficient photocarrier separation and exhibits superior redox ability in separated electrons and holes. Moreover, ternary composites have demonstrated enhanced photocatalytic activities and reinforced photostability. Ternary Z-scheme heterostructures constructed with g-C3N4 possess all the above-mentioned merits and provide a pioneering strategy for implementing photocatalytic systems for environmental and energy sustainability. A summary of the latest technological advancements toward design and fabrication in ternary all-solid-state Z-scheme (ASSZ) and direct Z-scheme (DZ) photocatalysts built on g-C3N4 is presented in this review. Furthermore, the review also discusses the application of ternary Z-scheme photocatalytic architecture established on g-C3N4.

Background

Metabolic syndrome (MetS) is defined by the presence of central obesity plus ≥two metabolic/cardiovascular risk factors (RF), with inflammation being a major disease-driving mechanism. Structured endurance exercise training (ET) may positively affect these traits, as well as cardiorespiratory fitness (V̇O2peak).

Aims

We explore individual ET-mediated improvements of MetS-associated RF in relation to improvements in V̇O2peak and inflammatory profile.

Methods

MetS patients from two randomized controlled trials, ExMET (n = 24) and OptimEx (n = 34), had performed 4- or 3-months supervised ET programs according to the respective trial protocol. V̇O2peak, MetS-defining RFs (both RCTs), broad blood leukocyte profile, cytokines and plasma proteins (ExMET only) were assessed at baseline and follow-up. Intra-individual changes in RFs were analysed for both trials separately using non-parametric approaches. Associations between changes in each RF over the exercise period (n-fold of baseline values) were correlated using a non-parametrical approach (Spearman). RF clustering was explored by uniform manifold approximation and projection (UMAP) and changes in RF depending on other RF or exercise parameters were explored by recursive partitioning.

Results

Four months of ET reduced circulating leukocyte counts (63.5% of baseline, P = 8.0e-6), especially effector subtypes. ET response of MetS-associated RFs differed depending on patients’ individual RF constellation, but was not associated with individual change in V̇O2peak. Blood pressure lowering depended on cumulative exercise duration (ExMET: ≥102 min per week; OptimEx-MetS: ≥38 min per session) and baseline triglyceride levels (ExMET: <150 mg/dl; OptimEx-MetS: <174.8 mg/dl). Neuropilin-1 plasma levels were inversely associated with fasting plasma triglycerides (R: −0.4, P = 0.004) and changes of both parameters during the ET phase were inversely correlated (R: −0.7, P = 0.0001).

Conclusions

ET significantly lowered effector leukocyte blood counts. The improvement of MetS-associated cardiovascular RFs depended on individual basal RF profile and exercise duration but was not associated with exercise-mediated increase in V̇O2peak. Neuropilin-1 may be linked to exercise-mediated triglyceride lowering.

In today’s rapidly evolving educational landscape, possessing digitalization competency is paramount for educators, as it enables them to effectively navigate the digital realm and engage with students in innovative ways. The global digitization of education contributes to a transformation in the context of competencies for higher education instructors. The objective of the current study is to ascertain the impact of this model on the development of competencies in contemporary educators and the enhancement of their skills. The research sample comprised 84 educators from the Karaganda Buketov University, who were categorized into two groups: control and experimental. Measurements of critical thinking levels (Critical Thinking Test Level I, CTT-I) and digital literacy (DigCompEdu CheckIn1) were administered to both groups before and after the program. Participants in the proprietary module constituted the sample of educators in the experimental group. The correlation of results indicates significant differences between the groups’ indicators before and after the module implementation. The positive dynamics of dependent variables resulting from the model implementation attest to the effectiveness of the current program in the context of developing educators’ critical thinking (p = 4.03 for critical thinking) and (p = 1.42 for digital literacy). In other words, the implementation of the model for the development of professional competencies among educators, based on the examined educational institution in Kazakhstan, enhances the critical thinking and digital literacy of educators. The practical application of this research lies in implementing this module as part of a systematic approach to competency development for educators in universities.

CILRT is an important work in the overhaul of nuclear power plants. VOCs from paints and cleaners used in the containment during the overhaul will migrate inside the containment, and the numerous rooms and compartments inside the containment make the air flow impeded, and the VOCs may be enriched to bring combustion risk. The complete fire risk analysis method includes volatilization kinetics of chemicals, mixture explosion limits, and numerical simulation of VOCs diffusion and migration. The volatilization rate at the lowest room temperature of 20°C is used as a conservative input, the complement of CAITA realistic model is used as the flow domain, and the geometry is appropriately simplified, and the steady ventilation process, the internal flow and the laws of diffusion and agglomeration of 12 kinds of VOCs gases in the 9-h pressure-holding process are investigated by Computational Fluid Dynamics. The simulation results of steady ventilation show that the VOCs gases are almost uniformly carried by the air to all spaces inside the containment, and the explosion risk is low. The concentration field of the steady ventilation process was taken as the initial boundary condition and unsteady state simulation of the 9-h holding pressure process was performed. The results show that the gas flow inside the containment basically stops after 3456 s of pressure holding. With the extension of time, the VOCs gases accumulate at the bottoms of the three lower layers of the containment under the effect of laminar diffusion and gravitational settling, where the total concentration of the mixed gases reaches the highest at the bottom of the lowest layer. The total concentration of the VOCs gas mixture was below the lower explosion limit throughout the 9-h pressure-holding process, and the explosion risk was low.

To address the challenges posed by the fast-charging demand of electric vehicles, causing feeder load and voltage imbalances during operation, this paper introduces a spatio-temporal pricing strategy tailored to enhance feeder operation equilibrium. This approach facilitates the spatio-temporal guidance of fast-charging loads for electric vehicles in operation. This paper begins by formulating a spatio-temporal distribution model for electric vehicle fast-charging loads, considering owners’ preferences. It further develops a behavioral model for the travel choices of electric vehicles, illustrating the impact of spatio-temporal electricity pricing at fast-charging stations on load distribution. Next, it proposes a multi-objective spatio-temporal pricing model and its solution method specifically designed for feeder-balance-oriented fast-charging stations. This model targets the minimization of the spatio-temporal imbalance in feeder voltage and load. It takes a comprehensive approach, considering the constraints of the spatio-temporal load distribution model and optimal power flow model. The resulting spatio-temporal pricing model for fast-charging stations is effectively solved using the extended Pareto evolutionary algorithm. To validate the effectiveness of the proposed method in achieving feeder balancing, this paper analyzes two examples: a self-built 29-node road network and a 9-node distribution network, as well as a 66-node road network and a 33-node distribution network in the Xinjiang region. The results show that the proposed method can effectively guide the charging of electric vehicles and make the load distribution more balanced.
Making predictions under interventions: a case study from the PREDICT-CVD cohort in New Zealand primary care

Background

Most existing clinical prediction models do not allow predictions under interventions. Such predictions allow predicted risk under different proposed strategies to be compared and are therefore useful to support clinical decision making. We aimed to compare methodological approaches for predicting individual level cardiovascular risk under three interventions: smoking cessation, reducing blood pressure, and reducing cholesterol.

Methods

We used data from the PREDICT prospective cohort study in New Zealand to calculate cardiovascular risk in a primary care setting. We compared three strategies to estimate absolute risk under intervention: (a) conditioning on hypothetical interventions in non-causal models; (b) combining existing prediction models with causal effects estimated using observational causal inference methods; and (c) combining existing prediction models with causal effects reported in published literature.

Results

The median absolute cardiovascular risk among smokers was 3.9%; our approaches predicted that smoking cessation reduced this to a median between a non-causal estimate of 2.5% and a causal estimate of 2.8%, depending on estimation methods. For reducing blood pressure, the proposed approaches estimated a reduction of absolute risk from a median of 4.9% to a median between 3.2% and 4.5% (both derived from causal estimation). Reducing cholesterol was estimated to reduce median absolute risk from 3.1% to between 2.2% (non-causal estimate) and 2.8% (causal estimate).

Conclusions

Estimated absolute risk reductions based on non-causal methods were different to those based on causal methods, and there was substantial variation in estimates within the causal methods. Researchers wishing to estimate risk under intervention should be explicit about their causal modelling assumptions and conduct sensitivity analysis by considering a range of possible approaches.
