What is a systematic review?
A systematic review is a comprehensive literature review conducted to answer a specific research question. Authors of a systematic review find, code, appraise, and synthesize all of the previous research concerning their question. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) outline the minimum amount of information that needs to be reported at the conclusion of a systematic review project. Other types of what are known as "evidence syntheses” include scoping, rapid, and umbrella reviews.
