|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 published report, the trial registration, protocol and statistical plan analysis were used in data extraction and risk of bias assessment. This is the report of one out of three cohorts of The PATCH trial (Prevention And Treatment of COVID-19 with Hydroxychloroquine). Crossover from placebo to HCQ was allowed upon disease progression/ virus confirmation. The study did not achieve its planned sample size because after the first planned interim analysis the trial was halted on the basis of a very low incidence rate among study participants. There was no change from trial registration to report in the intervention and control treatments, as well as the outcomes.|
