This teaching session covers the topic of selecting studies for inclusion in systematic reviews of interventions.

This session was last updated in 2022. While much of the core training is still relevant, trainers should check materials against the latest Cochrane Handbook and current editorial requirements.

Good news! We are currently refreshing all of our teaching sessions to ensure information is accurate, and to enhance ease of use and learning design (e.g. outcomes, interactivity, visuals etc). Watch out for updates to 'all teaching sessions', and email announcements from our Trainer's Network.
