Systematic Reviews

Systematic reviews synthesise the best available research evidence on a specific question. When well conducted, systematic reviews provide a sound and reliable basis for decision-making about public policy and provision of public services. These reviews use explicit and transparent procedures to identify all available research evidence relevant for a specific question.

To ensure that systematic reviews are reliable and replicable they must have a clear inclusion and exclusion criteria, an explicit search strategy and systematic procedures for data extraction, critical appraisal and analysis of included studies. When appropriate, findings from individual studies should be combined using statistical meta-analysis.
