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. 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 interpreting results), as well as more specialised topics (non-randomized studies, adverse effects, complex interventions, equity, economics, patient-reported outcomes, individual patient data, prospective meta-analysis, and qualitative research). The list of all author contributors of the Handbook is available here.
Key aspects of Handbook guidance are collated as the Methodological Expectations for Cochrane Intervention Reviews (MECIR). These provide core standards that are generally expected of Cochrane reviews. Each MECIR item includes a link to a relevant Handbook chapter.

The Handbook editorial team includes: Julian Higgins and James Thomas (Senior Scientific Editors); Jacqueline Chandler, Miranda Cumpston, Tianjing Li, Matthew Page and Vivian Welch (Associate Scientific Editors); Ella Flemyng (Managing Editor).
