Better evidence for a better world

A systematic review is an academic research paper that uses a method called 'evidence synthesis', which can include meta-analysis, to look for answers to a pre-defined question. The purpose of a systematic review is to sum up the best available research on that specific question.

An evidence and gap map is a visual presentation of the available rigorous research evidence for a particular policy domain. EGMs consolidate what we know and do not know about ’what works’, and provides a graphical display of areas with strong, weak or non-existent research evidence on the effect of interventions or initiatives.
