Among clinical trials, the reference standard is the randomized, double-blinded, placebo-controlled trial, which is designed to minimize bias in the selection of therapies or the interpretation of results.

I have written before about the limitations of clinical research in advancing medical practice. As I have said, it is literally impossible to study every clinically relevant question, and it is also impossible even in theory to use randomized controlled trials as the methodology for many of the questions that can be studied.
