How to read a nephrology systematic review

Abstract

A systematic review provides the best summary of evidence for clinical decision-making in nephrology by summarizing all the primary studies that evaluate a specific clinical question. By using rigorous and pre-specified methods, conclusions about the overall effect of an intervention can be more reliable, precise and comprehensive in a systematic review than those derived from individual studies. In this article, we describe the key components of a systematic review and meta-analysis. We summarize the features of a systematic review that should be looked for when considering the accuracy and validity of its results - particularly when applying the outcomes of a systematic review to a clinical question. © 2010 Asian Pacific Society of Nephrology.
