Systematic reviews

A brief overview of systematic reviews and resources to support producing one.

Search techniques for systematic reviews

The  search for a systematic review is based on the research question originally developed for the review. The goal of the search is to find all of the relevant studies, so it has to be comprehensive enough to capture all of the literature and to be performed in more that one resource.

Key points to include in a search strategy

Resources for search filters and hedges (pre-developed search terms for a topic or a study type).
