Abstract

The quality of the evidence is a keystone in the understanding of Evidence Based Medicine. Randomized controlled trials (RCTs) rank first among the research designs providing clinical evidence. Knowing about the design of clinical trials is not only the cornerstone of clinical research, but also is a requirement for any clinician who wants to learn about new findings of clinical research in his/her field. Many clinicians have good understanding as well as some misunderstandings about the design of clinical trials. This article is going to provide some crucial comments to be considered in conducting RCTs in order to help in production of better evidence for future of urology research through RCTs.
