A systematic review is a thorough summary of the scientific literature on a specific topic. A systematic review clearly states the process that was used to identify all published research on the topic under review. The authors of the systematic review critically appraise all individual studies and use appropriate statistical techniques to combine valid studies. Not all systematic reviews are equal. There is an art to performing a good systematic review and some authors excel at identifying and evaluating all published literature. At the end of the systematic review, the authors state whether the current research supports the effectiveness of a given therapy or not.
Healing Thresholds does not perform systematic reviews. We do, however, rely on them when preparing our fact sheets.
