What are systematic reviews?

A systematic review is an approach used in health, education and social policy (as part of evidence based policy or practice). It's much more than a 'literature review' - it follows a strict and rigorous methodology. The aim is to identify, select, synthesize and appraise all high quality research evidence relevant to a particular topic.

Five steps to a Systematic Review

1. Formulate your question.
2. Search for studies. 
3. Assess the quality of studies.
4. Summarise the evidence.
5. Interpret the findings.
