General comment |
In addition to all available versions of the published/pre-print article, the study registry and protocol were used in data extraction and risk of bias assessment. The study achieved the target sample size specified in the trial registry. There is no change from the registry in the intervention and control treatments, nor in the primary outcome. Some outcomes from the registry are not reported in the paper (e.g., mortality). The outcome adverse events is reported in the paper, but was not pre-specified in the trial registry/protocol. Of note: the report text states "The cases of respiratory failure in the two group were both 4", but the table shows 1 case for the Favipirivir group and 4 cases for the Umifenovir group.
