Risk of bias
Overall
The overall risk of bias reported in the table corresponds to the highest risk of bias for the outcomes assessed for the systematic review
Some concerns
General comment In addition to all available versions of the published article, the study registry, statistical analysis plan and protocol were used in data extraction and risk of bias assessment. Overall, the published study report reflects the protocol in methods and in results published. There are some small inconsistencies in the trial registry (recorded as "prospectively registered", but recruitment data already passed and between the registration and the published report (the primary outcome in the protocol and the report is not included in detail in the registration), but it is possible that these relate to the data entry interface or structure of the registry. The study achieved the target sample size specified in the registry.
