Systematic Review Resources

Rigorous and systematically laid out evidence needs to be the basis for effective policies that can improve the lives of people in developing countries.

Systematic reviews facilitate access to evidence that is valid beyond the context of a single project. They examine the existing evidence on a particular intervention or programme in low and middle income countries, drawing also on evidence from developed countries when pertinent.

This page outlines key resources for the producers and users of systematic reviews in international development and beyond. 

E- libraries and other resources

Collections of ongoing and completed systematic reviews which include reviews with relevance to low- and middle-income countries. 

Tools and guidelines

For producers of systematic reviews and users interested in learning more about the methodologies and uses of systematic review research.
