Literature Search

Your literature search should be as extensive as possible in to locate as evidence as possible, and to reduce reporting bias. 

Your review topic will guide which databases you choose. Using health-related databases is typically the most efficient way to identify relevant studies. When topics are specialized, cross-disciplinary, or involve emerging technologies, you will need to search additional databases.

Chapter 4.3 of the Cochrane Handbook for Systematic Reviews of Interventions provides guidance around sources to search, and search expectations.
