What kind of methodological standards are expected from systematic review?
There are many systematic review methods available (see for example Barnett-Page E, Thomas J (2009) ‘Methods for the synthesis of qualitative research: a critical review’, BMC Medical Research Methodology 9:59) and many guidelines for conducting systematic reviews including: Social, education and justice policy – Campbell CollaborationHealth sciences and policy – Cochrane CollaborationEducation, health and social welfare policy – EPPI-CentreEcology and conservation – Collaboration for Environmental Evidence DFID supports systematic reviews that employ the relevant methodology for the question asked and the studies reviewed. A statistical meta-analysis of qualitative studies will not be terribly useful. DFID recognizes that there are no standard methodologies for systematic reviews in international development and that this field contains many varied disciplines, from crop sciences to governance. DFID supports systematic reviews that adhere to the general principles of systematic review
