A systematic review is a review of a clearly formulated question that uses systematic and explicit methods to identify, select, and critically appraise relevant research studies. It collects and analyzes data from the included studies. Statistical methods like meta-analysis may be used to analyze and summarize the results. The gold standard is an individual participant data meta-analysis that models both study and individual characteristics.
