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
Low
General comment In addition to the published article, the trial registry, protocol, statistical analysis plan and supplementary appendices were used in data extraction and assessment of risk of bias. The primary outcome in the article reflected that in the registry. The study (n = 546) achieved the target sample size for the early futility assessment (n = 450), but recruitment was terminated as a result of the interim analysis so that the study did not achieve the target sample size for efficacy assessment (n = 1000).
