PROTOCOL: Methods used in the development, production and updating of evidence and gap maps: A scoping review.

ABSTRACT

Evidence and gap maps (EGMs) are an increasinly popular approach used in evidence synthesis. As an approach they address broad research questions, describing the existing evidence base, highlighting evidence gaps and providing an interactive visual tool for knowledge users. The purpose of this methodological study is to explore the the processes used in the development of EGM's and how they are reported. The aim is to better understand current practice and identify where clearer guidance is needed to support their production.
