Systematic Reviews & Evidence Based Reviews

An overview of systematic reviews and other evidence-based reviews.

Has your review already been done?

Before starting your search, make sure that someone else has not already done the same or similar work. Check both for previously registered protocols for work that is currently in progress, and for previously published systematic reviews.

Registering your protocol is highly recommended, as it can reduce bias in the systematic review process and to reduce the risk of duplicate efforts.
