In addition, 69% of the studies reported a conflict of interest statement, while not a single study reported using a pre-registered study protocol. b Using SYRCLE’s risk of bias tool, the risk of selection, performance, detection, attrition and other biases was assessed for the 88 studies included in this systematic review. The proportion of studies, expressed as a percentage, which have a low, unclear, or high risk of bias within the various bias categories.
