|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 all available versions of the published manuscript, the pre-print article, the study registry and protocol were used in data extraction and risk of bias assessment. This was a report of interim results of an adaptive trial evaluating 4 drugs: Remdesivir, Hydroxychloroquine, Lopinavir, and Interferon-β1a. No target sample size was pre-specified.
Quote: "The protocol stated “The larger the number entered the more accurate the results will be, but numbers entered will depend on how the epidemic develops… it may be possible to enter several thousand hospitalised patients with relatively mild disease and a few thousand with severe disease, but realistic, appropriate sample sizes could not be estimated at the start of the trial.” The Executive Group, blind to any findings, decided the timing of release of interim results."
Quote: "The hydroxychloroquine, lopinavir, and interferon regimens were discontinued for futility on, respectively, June 19, July 4, and October 16, 2020."
There was no change from the trial registration in the intervention and control treatments, nor in the primary and secondary outcomes.
This study was updated on December 9th using data from the published manuscript.
