Study designs: Part 8 - Meta-analysis (I)

Abstract

A systematic review is a form of secondary research that answers a clearly formulated research question using systematic and defined methods to identify, collect, appraise, and summarize all the primary research evidence on that topic. In this article, we look at meta-analysis – the statistical technique of combining the results of studies included in a systematic review.
