The link in the column "Overall risk of bias" provides access to a complete description of the assessment of each risk of bias domain with supports for judgement produced using the Revised Cochrane risk-of-bias tool for randomized trials RoB 2.

The risk of bias by domain as well as overall risk of bias reported in the table corresponds to the highest risk of bias for the outcomes assessed for the systematic review. The link in the column "Full description" provides access to the general characteristics of the study.
