Literature Reviews & Evidence Syntheses


This guide provides information and definitions about different types of literature reviews, or more broadly, an evidence synthesis. The term "evidence synthesis" might be new to you, but, in brief, it’s any method of identifying, selecting, and combining results from multiple sources. There are many types of evidence syntheses which will be defined throughout this guide.
