When are clinical trials beneficial for study patients and future patients? A factorial vignette-based survey of institutional review board members.
Article in BMJ open, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThe ethicists believe that the goal of clinical research is to benefit future and not current (trial) patients. Many clinicians believe that the clinical trial enrolment offers best management for their patients. The objective of our study was to identify the situations when a clinical trial is beneficial for the patients enrolled in the trial and future patients.
designFactorial vignette-based cross-sectional survey via the internet.
participantsInstitutional review board (IRB) members of the US Medical Schools.
main outcome measuresEach participant was invited to review 9 clinical vignettes related to (1) study approval and (2) the assessment if the study is designed to help future or current patients more.
resultsA total of 232 IRB members from 42 institutions participated. When considering approval of the trial, we found that uncertainty about treatment effects (OR=1.13; 95% CI 1.08 to 1.19) and requirement for continuation of standard therapy (OR=3.84; 95% CI 2.7 to 5.55) were the only statistically significant factors affecting IRB members' decisions to approve the study. The odds of IRB members approving a trial increased when a trial proposed to enrol patients with life-threatening versus chronic debilitating disease (OR=2.04; 95% CI 1.47 to 2.86). We also found that similar factors affected judgements related to the assessment whether the trial will benefit future or current patients more-(1) future patients: uncertainty (OR=1.27; 95% CI 1.18 to 1.37); continuation of standard treatment (OR=1.66; 95% CI 1.07 to 2.56); seriousness of condition (OR=1.78; 95% CI 1.15 to 2.28); (2) current patients: uncertainty (OR=1.54; 95% CI 1.4 to 1.7); continuation of standard therapy (OR=2.17; 95% CI 1.39 to 3.44).
conclusionsIRB members view the proposed studies to be beneficial for current patients and future patients if there is uncertainty regarding treatment effects and if studies do not require stopping the current treatment. This finding supports the design and use of pragmatic trials which may reduce therapeutic misconception and improve trial enrolment, speeding up therapeutic discoveries.
