It has been 20 years since the Cochrane Collaboration started the global effort to synthesize evidence to improve healthcare. Since 1997, the Cochrane Renal Group has produced over 100 systematic reviews that have collectively had an important impact on nephrology care, guidelines and policy. In this article, we reflect on the ongoing need for randomized trials and systematic reviews in contemporary nephrology and the achievements of the Cochrane Collaboration so far. We also describe some of the challenges in clinical research still faced by the nephrology community today.
