Motores de busca de dispositivos desempenham um papel importante no processo de rastreamento de vulnerabilidades. Entretanto, existem poucos estudos que analisam as capacidades desses sistemas. Nosso trabalho compara dois sistemas de busca populares, o Censys e o Shodan, no contexto da internet brasileira. Devido ao grande volume de dados gerados pelos motores de busca, implementamos uma abstração de dados única que simplifica consultas complexas e que permite a integração de dados externos complementares. Propomos um arcabouço para avaliar ambos os sistemas. Nossos resultados apontam diferenças significativas no modo de operação dos dois sistemas, sendo o Censys o sistema com maior cobertura de dispositivos no Brasil, enquanto o Shodan possui uma maior diversidade de serviços detectados e atualizações mais frequentes. A combinação dos dois motores aumenta a quantidade de serviços detectados e a taxa de varredura em até 1,8 vezes, ao mesmo tempo que obtemos mais detalhes sobre os serviços avaliados.

Authors: Abreu Diego , Abelém Antônio
Published: October 2024

Na era digital, a crescente sofisticação e variedade de ameaças cibernéticas destacam a importância de fortalecer a cibersegurança para proteger as redes atuais. Este estudo propõe uma abordagem para a detecção antecipada de ataques, utilizando a técnica Matrix Profile (MP) para analisar de forma online fluxos de dados de rede como séries temporais. Este método concentra-se na identificação de anomalias na rede como indicadores de ataques de rede, abordando as limitações dos sistemas de Aprendizado de Máquina existentes que dependem predominantemente de treinamento offline e têm dificuldades em reconhecer padrões de ataques novos ou não treinados. Nossa proposta foi avaliada em diversos cenários de ataque, demonstrando métricas de desempenho superiores quando comparado com métodos tradicionais como CUSUM, EWMA e ARIMA.
Constraint-Aware Deep Reinforcement Learning for vRAN Dynamic Placement
Authors: Almeida Gabriel M. , Abdel-Rahman Mohammad J. , Cardoso Kleber V.
Published: October 2024

The disaggregated and virtualized Radio Access Network (vRAN) is already present in 5G but tends to have increased adoption in 6G, mainly in the context of the Open RAN (O-RAN). Despite the potential benefits, the effective success of disaggregated vRAN depends on the efficient placement of Virtualized Network Functions (VNFs), which is influenced by the demand in the Radio Units (RUs). Several factors create dynamicity in this demand, but the number of users served by each RU is one of the most impacting. This problem has already been tackled in the recent literature, however, the works oversimplify important aspects that make their proposals inappropriate for real-world adoption. In this paper, we introduce a Deep Reinforcement Learning (DRL) agent that is constraint-aware, ensuring the solutions’ feasibility. We compare our DRL solution with existing optimization models and evaluate it under different scenarios, including the presence of Mobile Edge Computing (MEC) applications that compete for computing resources. Our contributions include a novel formulation, the implementation of a publicly available DRL agent, and insights into practical application scenarios for disaggregated vRAN optimization.

Detectando Heavy Hitters globalmente em dispositivos programáveis multi-pipes
Authors: Rodrigues Thiago Henrique Silva , Tavares Thiago Caproni , Verdi Fábio Luciano
Published: October 2024

Uma forma de contribuir para a gestão de redes, envolve detectar fluxos de tráfego de grande impacto, conhecidos como “Heavy Hitters”. Heavy Hitters são fluxos que conduzem a maior parcela de bytes transmitidos pela rede, consequentemente consumindo mais recursos. O uso de hardware programável, como switches e DPUs, permite a detecção desses fluxos diretamente no plano de dados da rede. Embora a literatura revele uma extensa análise da detecção em switches de pipe único, este estudo apresenta duas abordagens para identificar Heavy Hitters em switches programáveis com múltiplos pipes. Uma abordagem possui um acumulador no switch, que centraliza os dados provenientes de todos os pipes e se comunica com o plano de controle. Já na outra, as comunicações com o plano de controle são independentes para cada pipe. Ambas abordagens foram desenvolvidas, e validadas através de um emulador, demonstrando eficácia e melhoria na detecção em switches multi-pipes, comparado a switches de pipe único.
Atualização pelo Ar (OTA) de Dispositivos Embarcados Veiculares com Computação Confiável Fim-a-Fim
Authors: Thomaz Guilherme A. , Sammarco Matteo , Campista Miguel Elias M.
Published: October 2024

Os veículos conectados possuem softwares que precisam ser atualizados para corrigir vulnerabilidades e adicionar novas funcionalidades. As atualizações Over-the-Air (OTA) evitam que o proprietário leve o veículo até uma assistência técnica, mas abrem brechas para ataques que modificam os executáveis e colocam vidas em risco. Este trabalho propõe uma arquitetura de OTA que combina as duas tecnologias de segurança por hardware mais adotadas no mercado: o Intel SGX no servidor e o ARM TrustZone no cliente. O trabalho se diferencia por propor o uso de computação confiável fim-a-fim para proteger a arquitetura de atacantes capazes de controlar todo o sistema operacional, tanto no servidor quanto no veículo. A implementação utiliza o CACIC-DevKit no servidor e um dispositivo embarcado veicular com o sistema seguro OP-TEE. Os experimentos revelam que o impacto do uso de TEE é de apenas 2% do tempo total para transferência de um bloco de 1KB de software.

Authors: Grossi Arthur Böckmann , Costa Filho Roberto Irajá Tavares da , Gaspary Luciano Paschoal
Published: October 2024

Com a intensificação no uso de plataformas de videoconferência nos últimos tempos, a qualidade do serviço provido tornou-se de extrema importância. A troca de dados, de áudio e vídeo, entre os participantes de uma videoconferência depende de uma série de mecanismos e protocolos, os quais precisam funcionar corretamente para que a comunicação não sofra degradações. Este estudo examina o comportamento de plataformas de videoconferência, baseadas em WebRTC, quando submetidas a restrições de largura de banda. Nesta iteração, realiza-se uma análise sobre as plataformas Elos e Google Meet, utilizando uma abordagem baseada em indicadores cross layer para monitoramento de qualidade de serviço de videoconferência. Os resultados obtidos indicam que as plataformas utilizam abordagens distintas para lidar com cenários de limitação em sua capacidade de rede. Ao aprofundar a compreensão dessas diferentes estratégias de adaptação, o presente trabalho fornece subsídio para o desenvolvimento de novas estratégias de adaptação de qualidade e para estudos voltados à avaliação de QoE em plataformas de videoconferência.

Published: October 2024

O suporte a contratos inteligentes na Blockchain Ethereum propiciou a emergência de um novo ecossistema de finanças descentralizado e automatizado, denominado DeFi. Esse ambiente é altamente competitivo e seus protocolos vem sendo explorados em busca de vulnerabilidades que oferecem ganhos econômicos a usuários estratégicos. Recentemente, a fila de transações pendentes do Ethereum tornou-se alvo de especulações financeiras. Na esperança de obter algum lucro, atacantes monitoram continuamente a fila e tentam antecipar transações de outros usuários, inserindo estrategicamente suas transações antes e após a transação da potencial vítima, o que se tornou conhecido como ataque sanduíche. Neste artigo, avaliamos suspeitas de ataques sanduíche na Blockchain Ethereum durante o ano de 2023, atualizando os conhecimentos sobre esse ataque. Nossas análises baseadas em 113.774 dos 2.599.105 blocos processados demonstram a ocorrência de 1.553.362 especulações de ataques, com um lucro de em média USD 3.202,82 para os atacantes, fornecendo fortes evidências que ataques sanduíche continuam ocorrendo no ecossistema DeFi.

Authors: Oliveira Leonardo Azalim de , Silva Rodrigo Oliveira , Lima Pedro Campos , Pereira Antônio Marcos Souza , Valadares Júlia Almeida , Silva Edelberto Franco , Dantas Mário Antônio Ribeiro
Published: October 2024

A tecnologia 5G representa uma evolução nas redes móveis por conta do paradigma orientado a serviços que permite mais flexibilidade de gerenciamento e a possibilidade da aplicação da análise de dados. O 3GPP define a NWDAF como a função de rede responsável pela análise de dados no 5G, porém, a literatura ainda é escassa de trabalhos sobre esta função. A fim de preencher esta lacuna, este artigo investiga a NWDAF sob um conjunto de dados de uma rede 5G simulada utilizando modelos de aprendizado de máquina como classificadores de protocolos de rede. Os resultados apresentam acurácia em torno de 75%, e além disso, possibilitam a reprodutibilidade e investigações futuras em análise de dados em acordo com o especificado pelo 3GPP.

Authors: Moreira Rafael Gomes , Rocha Rafael Oliveira da , Chahud Leonardo Gonçalves , Pereira Junior Lourenço Alves
Published: October 2024

Sistemas de detecção de intrusão em rede baseados em aprendizado de máquina podem ser vulneráveis a ataques adversariais. Porém, a realização desses ataques demanda conhecimento de informações internas do modelo utilizado, que podem estar indisponíveis para o atacante. Este trabalho apresenta um método de roubo de modelo com o foco na equivalência da contribuição das características entre modelo alvo e substituto, bem como uma abordagem caixa-preta da técnica EBFA, chamada EBFA_BB. Em comparação com os ataques utilizados como baseline, o ataque proposto conseguiu criar modelos substitutos com, no mínimo, 10% a mais de equivalência das características mais importantes do modelo alvo.

Authors: Miranda Lívia Maria Bettini de , Garcia Rodrigo Dutra , Ueyama Jo , Ramachandran Gowri , Guerrini Fábio Müller
Published: October 2024

Organizations collaborate in industrial networks to share business risks, innovate, and deliver value-added products and services, relying on trust management. However, mistrust among stakeholders arises due to a lack of information transparency, coordination issues, and incentive misalignment. To overcome this problem, this work proposes a decentralized reputation system based on blockchain, smart contracts, and tokenization. Particularly, we address the problem of selecting partners for multi-stakeholder production through their token-based reputation. Our proof-of-concept evaluation results show that the proposed system is agnostic for Ethereum Virtual Machine-based (EVM) blockchains with low computational overhead.

Mehr Wertschöpfung und Wirkung durch prozessbasierte Beschaffung
Authors: Brandl Paul
Published: October 2024

So kann die Entwicklung nicht mehr lange weiter gehen! Der Personalmangel ist allerorts spürbar, die Suche nach Arbeitskräften ist vielerorts lesbar. Der Zeitdruck für das Personal wird zur Herausforderung. Kritiken an der Qualifikation und Motivation von Mitarbeiter:innen, umständlichen Regelungen und zu geringen Ressourcen steigen.

Darunter fällt etwa auch ein viel zu bürokratisches Qualitätsmanagement. Gefordert wird eine hohe Qualität bei gleichzeitig noch höherer Effizienz und Effektivität im Produktionsbereich sowie bei (sozialen) Dienstleistungen. Ein mehr an Personal bei gleicher Arbeitsweise ist nicht möglich und wird nicht zum gewünschten Output im Unternehmen führen. Ebenso wird ein höherer Outcome im Sinne der Kund:innenzufriedenheit oder schon gar nicht eine höhere gesellschaftliche Wirkung im Sinne des Impacts erreicht. Bleibt die Suche nach neuen Wegen durch organisatorische Veränderungen und neue Arbeitsweisen. Damit gehört der Einkauf im Sinne des Input–Output–Modells zur Vergangenheit. Der Preisvergleich reicht nicht mehr: Die prozessbasierte Beschaffung muss der Fokus sein.
Fiktion und juristische Begriffsbildung
Authors: Conti André Nunes
Published: October 2024

Legal fictions are usually defined as consciously false assumptions. This definition is suitable for distinguishing fictions from presumptions, but it conceals some important nuances about the role of fictions in a legal system. For this reason, this paper proposes an alternative definition of legal fictions as discrepancies between different conceptual systems. In doing so, it makes it possible to focus not primarily on external fictions, which consist in a discrepancy between legal terminology and colloquial language, but rather on internal fictions, which consist in a discrepancy between two versions of a legal conceptual system. The juxtaposition of two versions of a legal conceptual system makes it clear that the addition of an internal fiction, as the most trivial form of representation for the result of an analogy, increases the distinctiveness of a system in an expedient way, but at the cost of a significant loss of perspicuity. As long as the internal fiction plays only a marginal role, it can provide a clever and elegant solution. But when it assumes a structural role, it is accompanied by too great a loss of perspicuity, and is therefore an indication that the system could profitably be restructured by explicitly adjusting the meaning of some of its key concepts.
Burnout als Folge sexueller Belästigung am Arbeitsplatz: Eine empirische Studie in der Polizei
Authors: Clasen Julia , Taefi Anabel , Zähringer Ulrike , Stania Fanny
Published: October 2024

Das Erleben sexueller Belästigung am Arbeitsplatz (SBAA) kann vielfältige Auswirkungen auf die Betroffenen haben. Zu den wichtigsten Risikofaktoren gehören bestimmte organisationale Merkmale, die die Auftretenswahrscheinlichkeit von SBAA erhöhen. Diese Charakteristika legen nahe, dass SBAA innerhalb der Polizei gegenüber anderen Institutionen vermehrt auftreten könnte. Im vorliegenden Beitrag werden anhand der Daten einer quantitativen Studie, die sich an Beschäftigte einer Länderpolizei richtete (n=138), die Verbreitung von SBAA und deren Zusammenhang mit Burnout untersucht. Die Ergebnisse zeigen, dass ein hoher Anteil der Befragten Formen von SBAA erlebt hat. Insbesondere verbale Formen, aber auch non-verbale und physische Belästigungen traten auf. Polizistinnen waren häufiger betroffen als Polizisten. In multiplen Regressionen zeigten sich Zusammenhänge zwischen SBAA und Indikatoren für psychisches Befinden und Gesundheit. Moderationsanalysen ergaben hinsichtlich der Geschlechtszugehörigkeit keine differenziellen Wirkungen von SBAA auf das psychische Befinden. Trotz einiger methodischer Limitationen legt dieser erste empirische Blick in die „geschlossene Organisation“ Polizei nahe, dass SBAA einen bedeutsamen Problembereich im Alltag der Polizist:innen darstellt, der in einem relevantem Ausmaß mit negativen Konsequenzen für die psychische Gesundheit der Betroffenen verbunden ist.
Vom Lügen und Fälschen: Abweichendes Verhalten in der COVID-19-Pandemie
Authors: Helbing Alexander , Krumpal Ivar
Published: October 2024

Ziel der vorliegenden Studie ist es, Normbrüche in der COVID-19 Pandemie zu erforschen. Im Zentrum steht die Messung und Prävalenzschätzung in Bezug auf Impfnachweisfälschungen und Lügen in Bezug auf den eigenen Impf- und Teststatus. Es wurde ein Online-Survey (n = 2.750) mit einem integrierten Methodenexperiment durchgeführt. Neben einer Direktbefragung (n = 549), wurde zusätzlich die Item Count Technik eingesetzt (n = 2.201), um das Ausmaß sozial erwünschten Antwortverhaltens einzuschätzen. Die Ergebnisse zeigen, dass sich in der Befragung mit der anonymeren Item Count Technik zwar etwas mehr Befragte zu abweichendem Verhalten bekennen als in der Direktbefragung. Diese Differenzen sind jedoch statistisch nicht signifikant. Insgesamt deuten unsere Befunde auf ein beachtliches Dunkelfeld von Normbrüchen hin.

Arbeitsscheu, verwahrlost, gefährdet
Authors: Wenger Sebastian
Published: October 2024

During the period of National Socialism and in the post-war years, the state in Germany had a restrictive attitude towards so-called “asocials”. They were stigmatized and persecuted because of their deviant behaviour. This study sheds light on the actors involved and their networks as well as the practice of forcibly committing social misfits 1934–1959 to the work and detention centers of the city of Stuttgart. These were established in the 1930s in cooperation with the Gustav Werner Stiftung zum Bruderhaus in Göttelfingen and in Buttenhausen. The monograph also documents the everyday (working) life of the minors and adults housed in the institutions.

Necessary conditions for graph isomorphism problem: polynomial time algorithms
Authors: Garimella R.
Published: October 2024

In this research paper, it is proved that two arbitrary graphs are isomorphic only if the quadratic forms associated with the two adjacency matrices are same(upto reordering the monomials). Based on the proof, a polynomial time algorithm is designed for testing necessary condition for isomorphism of graph (i.e. effectively deciding whether two graphs are isomorphic). The algorithm requires O(N 3 ) comparison operations. Also, a polynomial time algorithm for checking necessary condition on whether two graphs are isomorphic is designed under the condition that the associated adjacency matrices are non-singular and are related through a symmetric permutation matrix. The algorithms are essentially based on linear algebraic concepts related to graphs. Also, some new results in spectral graph theory are discussed.

The image of Russia in modern British historical novels
Authors: Загрядская Н.А.
Published: October 2024

статья посвящена созданию образа России в современной британской исторической литературе. Особое внимание обращается на трактовку понятий «исторический роман» и «роман об историческом прошлом». Автором затрагивается вопрос происхождения и развития жанра исторического романа, его трансформация. В статье дается определение понятия «миф о России», дается краткий обзор литературы по данному вопросу. Исследование проводится на материале романов современных британских писателей Э. Резерфорда "Russka" и Э. Элпстен "Tsarina". Романы анализируются с точки зрения их жанровой принадлежности, а также особенностей создания образа России в рамках сложившегося «мифа о России. Автор проводит сравнение двух произведений, останавливаясь на специфике каждого романа, выделяя сходства и различия в подходе к созданию как образа страны в целом, так и описанию отдельных исторических персоналий. Изображение различных исторических событий также подвергается рассмотрению. В заключении делается вывод об определенной стереотипности подхода авторов обоих произведений и устойчивости сложившегося мифа о России. Намечаются перспективы дальнейшего исследования данной проблемы как в области литературоведения, так и в области стилистики текста.

the article is devoted to the creation of the image of Russia in modern British historical literature. Special attention is paid to the interpretation of the concepts of "historical novel" and "novel about the historical past". The author touches upon the question of the origin and development of the genre of the historical novel, its transformation. The article defines the concept of "the myth of Russia" and provides a brief overview of the literature on this issue. The research is based on the novels of modern British writers E. Rutherford "Russka" and E. Alpsten "Tsarina". The novels are analyzed from the point of view of their genre affiliation, as well as the peculiarities of creating an image of Russia within the framework of the established "myth of Russia. The author compares the two works, focusing on the specifics of each novel, highlighting similarities and differences in the approach to creating both the image of the country as a whole and the description of individual historical figures. The depiction of various historical events is also under consideration. Finally, the author makes a conclusion that there is a certain stereotypical approach of the authors of both works and the stability of the established myth about Russia. Prospects for further research of this problem are outlined both in the field of literary criticism and in the field of text stylistics.
New year in Russian and Chinese linguistic cultures: features of the verbalization of the the HOLIDAY concept
Authors: Пэй Х.
Published: October 2024

в статье анализируется специфика понимания Нового года и его атрибутики в контексте вербализации концепта ПРАЗДНИК. Автор исследования обращается к данному празднику как к одному из наиболее значимых в обоих лингвокультурах – русской и китайской. Исследование основано на ассоциативном и рисуночном экспериментах. Отмечена специфика ассоциативного эксперимента и перспективы его применения для анализа концептов; выделены особенности рисуночного эксперимента и возможности его применения в лингвистике. Проанализированы данные, полученные путем анкетирования русских и китайских респондентов в течение 2019-2021 годов. На основе анализа полученных данных (вербальных и невербальных) отмечено, что ассоциативы у носителей двух лингвокультур разнятся, поскольку традиции празднования Нового года у них также различны. Однако зафиксированы и совпадения, указывающие в первую очередь на значимость праздника в жизни и русских, и китайцев. Автор исследования приходит к выводу, что анализ специфики новогодних праздников в контексте ассоциативного и рисуночного эксперимента показывает продуктивность подобных исследований и дает возможность аналогичной работы по отношению к другим национальным праздникам носителей русской и китайской лингвокультур.

the article analyzes the specifics of understanding the New Year and its attributes in the context of the verbalization of the HOLIDAY concept. The author of the study refers to this holiday as one of the most significant in both linguistic cultures – Russian and Chinese. The research is based on associative and pictorial experiments. The specificity of the associative experiment and the prospects of its application for the analysis of concepts are noted; the features of the drawing experiment and the possibilities of its application in linguistics are highlighted. The data obtained by questioning Russian and Chinese respondents during 2019-2021 are analyzed. Based on the analysis of the data obtained (verbal and non-verbal), it is noted that the associatives of the speakers of the two linguistic cultures differ, since the traditions of celebrating the New Year are also different. However, coincidences have also been recorded, indicating primarily the importance of the holiday in the lives of both Russians and Chinese. The author of the study concludes that the analysis of the specifics of New Year's holidays in the context of an associative and pictorial experiment shows the productivity of such studies and makes it possible to work similarly with respect to other national holidays of native speakers of Russian and Chinese linguistic cultures.

The legal status of municipal entities as a result of the constitutional reforms
Authors: Гатауллин З.Ш.
Published: October 2024

в данной статье рассматриваются результаты конституционной реформы 2020 года, которые затронули правовое положение муниципальных образований. Ранее, в дореформенный период, т.е. до 2020 г. конституционно-правовые нормы наделяли органы местного самоуправления полномочиями самостоятельно решать определённый перечень вопросов. Прежняя государственная политика относительно муниципальных образований была направлена на сближение власти к населению. Причем местное население самостоятельно формировало эту самую власть, которая отчитывалась перед этим самым населением. Автономность муниципальных образований не давала возможность государства вмешиваться в процесс выборов глав и депутатов на местах, которые были самостоятельны, не являлись представителями государства. Более того ни один государственный чиновник не мог вмешиваться в процесс решения вопросов местного значения главами муниципалитетов и местных депутатов. Отсутствие достаточных финансовых возможностей для решения вопросов местного значения приводило к зависимости от трансфертов власти субъектов РФ и федерального уровня власти. Безусловно, в этих условиях о какой-то реальной самостоятельности утверждать не приходится. Западная модель демократии на местном уровне видимо не прижилась, похоже возвращаемся к испытанному временем советскому демократическому централизму, подотчетностью снизу доверху.

this article examines the results of the 2020 constitutional reform, which affected the legal status of municipalities. Earlier, in the pre-reform period, i.e. until 2020, constitutional and legal norms gave local governments the authority to independently resolve a certain list of issues. The previous state policy regarding municipalities was aimed at bringing the authorities closer to the population. Moreover, the local population independently formed this very government, which was accountable to this very population.The autonomy of municipalities did not allow the state to interfere in the process of electing heads and deputies on the ground, who were independent and were not representatives of the state. Moreover, no government official could interfere in the process of resolving issues of local importance by the heads of municipalities and local deputies. The lack of sufficient financial resources to resolve issues of local importance led to dependence on transfers of power from the subjects of the Russian Federation and the federal level of government. Of course, in these conditions, there is no need to assert any real independence. The Western model of democracy at the local level has apparently not caught on, it seems that we are returning to the time-tested Soviet democratic centralism.

State Hegemony In Global Civil Society: The Articulation Of Indonesia's Ecpat Hegemony In The Process Of Securitization Of Child Sexual Exploitation

Published: October 2024

The process of securitization of anti-child sexual exploitation norms (anti-ESA) carried out by ECPAT Indonesia relies on two hegemonic discourses, namely the global hegemonic discourse on children's rights and the political discourse on state hegemony. Looking at using the Securitization Theory, this study finds that ECPAT Indonesia disseminates the ESA threat to the local community as a securitization audience but without conducting equivalent socialization. This inequality arises due to the securitization model carried out by ECPAT Indonesia which is imposing through state hegemony instead of accommodating differences in norm structures between global and local communities. This argument is supported by using critical discourse analysis that looks at interviews with ECPAT Indonesia and the press releases they issue. In researching this issue, this study finds that ECPAT Indonesia does design their operations by utilizing the two hegemonies that have been mentioned.
Early Neurological Deterioration and Time to Start Dual Antiplatelet Therapy in Patients With Acute Mild-to-Moderate Ischemic Stroke: A Pre-Specified Post Hoc Analysis of the ATAMIS Trial

Background and Purpose This study comprised a post hoc analysis of the Antiplatelet Therapy in Acute Mild to Moderate Ischemic Stroke (ATAMIS) trial aiming to determine whether the effect of dual antiplatelet therapy compared with that of monotherapy on preventing early neurological deterioration (END) differed according to the time from stroke onset to antiplatelet therapy (OTT).Methods In the ATAMIS trial, patients were divided into two subgroups: OTT from 0 to 24 hours (0–24 h group) and OTT from 24 to 48 hours (24–48 h group). We conducted multivariate regression analysis with continuous and categorical OTT to detect the effect of antiplatelet therapy. The primary outcome was END at 7 days, defined as an increase in the National Institutes of Health Stroke Scale (NIHSS) score of more than two points compared with the baseline. The safety outcomes were bleeding events and intracranial hemorrhage within 90 days.Results A total of 2,915 patients were included. With respect to END at 7 days, clopidogrel plus aspirin showed a lower proportion than aspirin alone across continuous OTT (4.8% vs. 6.7%; adjusted risk difference, -1.9%; 95% confidence interval [CI], -3.6% to -0.2%; P=0.03), and was lower in the 0–24 hours group (5.7% vs. 9.2%; adjusted risk difference, -3.7%; 95% CI, -5.5% to -2.0%; P<0.01), but similar in the 24–48 hours group (3.5% vs. 2.9%; adjusted risk difference, 0.6%; 95% CI, -0.8% to 2.0%; P=0.40). We identified a significant interaction between the treatment effect and time subgroup with respect to the primary outcome (P=0.03). The occurrence of bleeding events and intracranial hemorrhage was similar in the time subgroup.Conclusion For patients with acute mild-to-moderate ischemic stroke, clopidogrel plus aspirin was associated with a lower risk of END at 7 days than aspirin alone when it was started within 24 hours of symptom onset.
