How to Conduct a Systematic Review

What is a Systematic Review?

Systematic Review: a high-level overview of primary research on a particular research question that tries to identify, select, synthesize and appraise all high quality research evidence relevant to that question in order to answer it. 

Meta-Analysis: a quantitative statistical analysis of several separate but similar experiments or studies in order to test the pooled data for statistical significance [often found within systematic reviews, but not the same].   

 All meta-analyses should be part of a systematic review, but not all systematic reviews will include a meta-analysis.

Systematic Review vs. Literature Review

It’s common to confuse systematic and literature reviews because both are used to provide a summary of the existing literature or research on a specific topic. This table provides a detailed explanation as well as the differences between systematic and literature reviews.
