How to use a CASP randomised controlled trial (RCT) checklist
In this module, we describe the 11 questions in the CASP randomised controlled checklist, explaining why each question is important to the critical appraisal of a randomised controlled trial and the main issues you need to consider when answering each question. Apart from these explanations, to illustrate how to use the CAST RCT checklist, we answer each question using information from the critical appraisal of a paper in the published literature. At the end of the module, we look at the challenges involved in assessing whether the results of a randomised controlled trial are generalizable and robust enough to be used in routine practice with your local population.
