Welcome to the Cochrane Collaboration’s Open Learning Material for Cochrane reviewers. Performing a Cochrane review requires skills that may be new to you, including the formulation of appropriate questions, literature-searching, critical appraisal, statistical analysis and interpretation and application of your findings. This material is designed to accompany the Cochrane Handbook for Systematic Reviews of Interventions in helping you gain these skills and complete your review. It does NOT replace the Handbook (see ‘Limitations of materials’ section below), instead it acts as a training supplement and provides a framework to progressing through the Handbook with examples and activities along the way.

This material will take a step-by-step approach to Cochrane reviews, exploring each step individually, signposting appropriate links and references and providing examples and activities to help you make sense of the information. The material is organised in modules, each module relating to consecutive sections of a review. Review authors may wish to complete each module as they start working on the corresponding part of their review. There are also some additional modules relating to issues that do not occur in all reviews.

Sections of the Handbook you need to read, extra references, and activities are listed at the beginning of the module so you know what you will need to complete for that module. These are referenced again in places that are relevant throughout the text of the module. These references are clearly marked in the margin using the symbols below. In electronic versions, the icons in the margin serve as a link to the Cochrane Handbook for Systematic Reviews of Interventions or other reference material. In paper versions they act to guide you to the appropriate place in the reference.

Also in the margin are brief summary notes, highlighting the important learning points.

All the references are freely available, either in the text or on the Internet, excepting the optional reference referred to in Module 6 (and useful to have in general):

Egger M, Davey Smith G, Altman D (eds). Systematic Reviews in Health Care. BMJ 2001.

Development of these materials

These Open Learning Materials were developed based on version 4.1.5 of the Reviewers' Handbook in 2002. They were compiled using open learning strategies in a collaborative project between several Cochrane Centres and the Cochrane Statistical Methods Group. The Handbook Advisory Group of the Cochrane Collaboration approved these materials for use in 2002.

Editing of materials

The content of these materials has not been updated since 2002 and should therefore be used with caution. Editing of these materials was conducted in 2009 with the sole purpose of re-aligning references with relevant sections of the Cochrane Handbook for Systematic Reviews of Interventions (Version 5.0.1) and updating information regarding Review Manager 5 software. These changes were intended as a temporary measure only in order to retain the usefulness of these materials while a decision is made regarding the necessary updating and future use of this resource (please see the note below regarding important limitations of these materials as a training resource). 

Limitations of materials: An important note regarding the Cochrane Handbook for Systematic Reviews of Interventions

The materials presented here are intended only as an introduction to some of the key concepts and methodology for conducting Cochrane systematic reviews of interventions. There are significant limitations in the information available in these materials for some methods in the review process, especially ‘Risk of bias’ assessment and ‘Summary of findings’ tables. These materials should not be considered as a stand-alone resource, and users must refer to the most recent version of the Handbook for the most up to date and comprehensive information for conducting a Cochrane review.

At the time of last editing these materials, the most current version of the Cochrane Handbook for Systematic Reviews of Interventions was Version 5.0.1 updated in September 2008. The most recent version of the Handbook can be accessed online at http://www.cochrane-handbook.org/.
