What is a clinical evidence statement?
A clinical evidence statement is a summary statement that is included in each review chapter, and which summarises the key features of the clinical effectiveness evidence presented. The wording of the evidence statements reflects the certainty or uncertainty in the estimate of effect. The evidence statements are presented by outcome and encompass the following key features of the evidence: The number of studies and the number of participants for a particular outcome; An indication of the direction of clinical importance (if one treatment is beneficial or harmful compared to the other, or whether there is no difference between the 2 tested treatments).
