Evidence and Gap Maps

Evidence and Gap Maps (EGMs) provide a visibly accessible overview of evidence from systematic reviews, impact evaluations and primary studies. They highlight the availability of the evidence, as well as certain characteristics, such as confidence ratings of the systematic reviews. A defining feature of EGMs is that they are structured around a framework (matrix) designed to reflect the relevant interventions and outcomes in a particular area. When the framework is populated with available studies and reviews, it highlights ‘absolute gaps’, where few or no studies exist. The main uses for an evidence and gap map are to guide policy makers and practitioners to available evidence that supports decision-making, and to inform research priorities in order to fill evidence gaps. Evidence and gap maps, however, do not summarize what the evidence says.  The talk will discuss what are evidence maps, how are they used, and ongoing initiatives by Campbell Collaboration in this area.    

Dr Ashrita Saran has been working as an Evidence Synthesis Specialist with Campbell Collaboration since 2017, leading the development of Campbell discussion paper on Evidence and Gap Map. Ashrita is the lead author and co-author of various published and on-going Campbell evidence and gap maps and systematic reviews, including ‘Mega Map on child welfare’ and ‘Evidence and gap map on people with disabilities’. She is an Epidemiologist with an expertise in systematic reviews and information science and has over 5 years of experience in public health research and management. Current research areas are education, child welfare and international development.
