The Campbell Collaboration is an international research network that produces systematic reviews of the effects of social interventions in Crime & Justice, Education, International Development, and Social Welfare.

This guide is recommended as a source of good practice by agencies such as the National Institute for Health Research Health Technology Assessment (NIHR HTA) programme, and the National Institute for Health and Clinical Excellence (NICE), and has been used widely both nationally and internationally. Their aim is to promote high standards in commissioning and conduct, by providing practical guidance for undertaking systematic reviews evaluating the effects of health interventions.

Provides guidance to authors for the preparation of Cochrane Intervention reviews (including Cochrane Overviews of reviews).

Handbook for grading the quality of evidence and the strength of recommendations using the GRADE approach. Updated October 2013.

These guidelines complement Sections 3 to 11 of the Cochrane Reviewers’ Handbook
(http://www.cochrane.org/resources/handbook/index.htm). The content has been prepared
by health promotion and public health researchers, decision-makers and practitioners experienced with both the use and conduct of systematic reviews. While these guidelines were originally developed to support the conduct of systematic reviews, they are also important for the conduct of primary research and for more informal reviews of research evidence. Many of the topics may not be unique to health promotion and public health reviews, but they are issues that are important in enabling research to be used in public health policy and practice decision-making.

The Joanna Briggs Institute (JBI) is the international not-for-profit, research and development centre within the Faculty of Health Sciences at the University of Adelaide, South Australia. The Institute collaborates internationally with over 70 entities across the world. The Institute and its collaborating entities promote and support the synthesis, transfer and utilization of evidence through identifying feasible, appropriate, meaningful and effective healthcare practices to assist in the improvement of healthcare outcomes globally.
