A quick guide to introduce you to systematic reviews

Systematic reviews

What are systematic reviews?

A systematic review is a summary of all of the literature on a particular topic, that meets pre-defined eligibility criteria.

The Cochrane Collaboration definition:

"A systematic review summarises the results of available carefully designed healthcare studies (controlled trials) and provides a high level of evidence on the effectiveness of healthcare interventions. Judgments may be made about the evidence and inform recommendations for healthcare.
