Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Input: Consider Input: To develop a scale and survey the measurement of patient adherence and patient recruitment, and to explore how these methods impact the results in randomized controlled trials of interventions to improve patient adherence to medications.', 'Analytic survey of a purposively selected sample of patient adherence intervention trials from a systematic review, assessing the quality of adherence measurement and patient recruitment methods.', 'We identified 44 different measures of adherence, with qualities ranging from valid and objective to unreliable and subjective. The median overall quality of measures of adherence was 5 (interquartile range [IQR], 3; range, 0-9, 9 is high quality). The quality of the measures was associated with variation in the estimate of adherence (Spearman r\xa0=\xa00.66; 95% confidence interval: 0.39, 0.83). The median overall quality of patient recruitment methods was 2 (IQR, 1; maximum score 6, higher is better). There was no significant correlation between the power of the trial to detect an effect and the quality of the patient recruitment methods.

Output: Are adherence measurement and patient recruitment methods poor in intervention trials to improve patient adherence?


Input: Consider Input: Proinflammatory cytokines have the potential to activate the hypothalamo-pituitary-adrenocortical (HPA) axis, and HPA axis hyperactivity is also encountered in depression. Therefore, the induction of depressive symptoms by interferon-alpha (IFN-alpha) may be mediated by changes in the cytokine network and the HPA axis.', 'In 17 hepatitis C patients undergoing IFN-alpha treatment, depressive symptoms were measured using the Montgomery-Asberg Depression Rating Scale (MADRS). In addition, serum cytokine concentrations were measured. Saliva was collected five times over the course of a day in order to assess daily average cortisol (DAC) and awakening response. Assessments were carried out at baseline and six later time points after starting treatment.', 'During treatment, the increases in the MADRS were significantly and positively correlated with soluble interleukin (IL)-2 receptor, tumor necrosis factor alpha (TNF-alpha), and IL-6. There were no significant associations between the DAC or cortisol awakening response with the MADRS score.

Output: Are interferon-alpha-induced depressive symptoms related to changes in the cytokine network but not to cortisol?


Input: Consider Input: Acid reflux has been associated with poorer outcomes after lung transplantation. Standard pre-transplant reflux assessment has not been universally adopted. Non-acid reflux may also induce a pulmonary inflammatory cascade, leading to acute and chronic rejection. Esophageal multichannel intraluminal impedance and pH testing (MII-pH) may be valuable in standard pre-transplant evaluation. We assessed the association between pre-transplant MII-pH measures and early allograft injury in lung transplant patients.', 'This was a retrospective cohort study of lung transplant recipients who underwent pre-transplant MII-pH at a tertiary center from 2007 to 2012. Results from pre-transplant MII-pH, cardiopulmonary function testing, and results of biopsy specimen analysis of the transplanted lung were recorded. Time-to-event analyses were performed using Cox proportional hazards and Kaplan-Maier methods to assess the associations between MII-pH measures and development of acute rejection or lymphocytic bronchiolitis.', 'Thirty patients (46.7% men; age, 54.2 years) met the inclusion criteria. Pre-transplant cardiopulmonary function and pulmonary diagnoses were similar between outcome groups. Prolonged bolus clearance (hazard ratio [HR], 4.11; 95% confidence interval [CI], 1.34-12.57; p = 0.01), increased total distal reflux episodes (HR, 4.80; 95% CI, 1.33-17.25; p = 0.02), and increased total proximal reflux episodes (HR, 4.43; 95% CI, 1.14-17.31; p = 0.03) were significantly associated with decreased time to early allograft injury. Kaplan-Meier curves also demonstrated differences in time to rejection by prolonged bolus clearance (p = 0.01) and increased total distal reflux episodes (p = 0.01). Sub-group analysis including only patients with MII-pH performed off proton pump inhibitors (n = 24) showed similar results.


Output: Are pre-transplant impedance measures of reflux associated with early allograft injury after lung transplantation?
