  30. What is a Systematic Review? Systematic review A review of a clearly formulated question that uses systematic and explicit methods to identify, select, and critically appraise relevant research, and to collect and analyze data from the studies that are included in the review. Statistical methods (meta-analysis) may or may not be used to analyze and summarize the results of the included studies. Meta-analysis The use of statistical techniques in a systematic review to integrate the results of included studies. Sometimes misused as a synonym for systematic reviews, where the review includes a meta-analysis. From: Cochrane Collaboration athttp://www.cochrane.org/resources/glossary.htm

  31. Systematic Reviews assess randomized trials and provide a comprehensive summary of the available evidence. Over 800 international journals are searched to locate articles. a Systematic Reviews contain all known reference to trials on a particular intervention. Evidence is assessed with explicit quality criteria to minimize bias ensure reliability. Trials that meet assessment criteria can be combined to produce a more statistically reliable result. Data from studies are often combined statistically to increase the power of the findings of numerous studies, which on their own may be too small to produce reliable results. Authors, who participate with the Cochrane Collaboration, appraise and synthesize evidence from as many relevant scientific studies as possible.
