Abstract

THE RANDOMIZED controlled trial (RCT), more than any other methodology, can have a powerful and immediate impact on patient care. Ideally, the report of such an evaluation needs to convey to the reader relevant information concerning the design, conduct, analysis, and generalizability of the trial. This information should provide the reader with the ability to make informed judgments regarding the internal and external validity of the trial. Accurate and complete reporting also benefits editors and reviewers in their deliberations regarding submitted manuscripts. For RCTs to ultimately benefit patients, the published report should be of the highest possible standard. For editorial comment see p 649. Evidence produced repeatedly over the last 30 years indicates a wide chasm between what a trial should report and what is actually published in the literature. In a review of 71 RCTs with negative results published between 1960 and 1975, the authors reported that the vast

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
