|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
|General comment||In addition to the pre-print article, the study registry was used in data extraction and risk of bias assessment. The study did not achieve the target sample size specified in the trial registry. The dosage of medication was not reported in the study, therefore we are unable to determine if the were any changes from the trial registration in the intervention treatments. The primary outcome indicated in the registry reflects the primary outcome reported in the paper. Only serious adverse events were reported (i.e., non-serious adverse events are not reported).|
