The Cochrane Handbook for Systematic Reviews of Interventions is the official guide that describes in detail the process of preparing and maintaining Cochrane systematic reviews on the effects of healthcare interventions. The current complete version of the Handbook is 5.1 (updated March 2011), edited by Julian Higgins and Sally Green.

All authors should consult the Handbook for guidance on the methods used in Cochrane systematic reviews. The Handbook includes guidance on the standard methods applicable to every review (planning a review, searching and selecting studies, data collection, risk of bias assessment, statistical analysis, GRADE and intepreting results), as well as more specialised topics (non-randomized studies, adverse effects, economics, patient-reported outcomes, individual patient data, prospective meta-analysis, qualitative research, reviews in public health and overviews of reviews).

We produced a limited number of Version 5.2 chapters in PDF format only. These chapters are 1, 8, 9, 10, 11, 12, and 21 and are available as pdf versions for Cochrane members. These chapters only include minor edits to improve clarity, some limited new material and updating. There are currently no substantive changes to methods in these chapters. For more details see the What's new? page.
