Editors' Update: June 2017
Following the introduction of the Methodological Expectations for Cochrane Intervention Review (MECIR) standards, we set out to produce a minor Handbook update, Version 5.2. Due to limited editorial capacity, a limited number of interim updates for Version 5.2 have been produced. The new chapters are 1, 8, 9, 10, 11, 12, and 21 and are available as pdf versions for Cochrane members. The new chapters include minor edits to improve clarity, some limited new material and updating. There are no substantive changes to methods. For more details see the What's new? page. The Handbook editorial team will now proceed to the full production of Version 6 of the Handbook, to be released in 2018. Senior Scientific Editors Julian Higgins and James Thomas have reorganized some material to include recent developments. There are also several new chapters including writing a protocol, equity and specific populations, complex interventions, network meta-analysis, and synthesizing findings using non-statistical methods.
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).
Official translations of the Handbook are also available in Spanish and Simplified Chinese (see links above right).
You can also access the Handbook in the following ways:
- In RevMan: the Handbook can be accessed offline through the Help menu of Cochrane's review production software.
As a textbook: Version 5.0.2 of the Handbook was published in by Wiley-Blackwell in September 2008 and is still available for sale. Note that this is no longer the most current version of the Handbook, and readers should consult the What's New section for more information.
Printable (PDF) versions of all chapters (Version 5.2) are available to registered Cochrane contributors (Archie login required).
Our Glossary includes definitions of methodological and organisational terms as used by Cochrane.
