|Risk of bias
The overall risk of bias reported in the table corresponds to the highest risk of bias for the outcomes assessed for the systematic review
In addition to the published article, the study registry (retrospective), protocol and statistical analysis plan (retrospective) was used in data extraction and risk of bias assessment. Outcomes for adverse and serious adverse events were extracted from the result section of the study registry.Target sample size specified in the registry and protocol was achieved. There is no change from the trial registration or protocol in the intervention and control treatments or in the outcomes. However, the study registry and protocol were retrospective and therefore interpreted with caution. Denominators for SAEs/withdrawal due to AEs and Mortality do not seem to include the participants with these outcomes.
