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	High
General comment	In addition to all available versions of the published/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. There is no change from the trial registration in the intervention and control treatments. The initial inclusion criteria included mild patients who were then removed after randomization. Table 1 reported characteristics for moderate patients only. 5 additional patients excluded before outcome analysis because they were asymptomatic. No pre-specified statistical analysis plan. Statistical measures (OR, RR, HR) were not reported; PO reported as median days (IQR). Data analysis is pending required information on outcomes
