Systematic Reviews

Systematic review

Description

It combines the strength of a critical review with exhaustive search processes and strategies. A systematic review attempts to collate all empirical evidence that fits pre-specified eligibility criteria in order to answer a specific research question.

The overarching purpose of a systematic review is to identify, analyse, appraise, and arrive at a considered and balanced judgement. Individual sources of research are gathered and evaluated side-by-side. Reviewers will rigorously create a record of the origin of the information and data they find, summarise and appraise each piece of evidence according to a strict criteria, and synthesise findings based on the primary source material in their review.
