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.
