Microbiology Evaluable Set (MES) consisted of all randomized subjects with detectable Log10 SARS-CoV-2 viral load at baseline and at least one non-missing postbaseline viral load assessment. Microbiology evaluable subjects were analyzed according to their randomized treatment. SARS-CoV-2 viral load (log 10 copies/mL) was reported as below.~* Number of copies/mL;~* \<Number of copies/mL, if detected but under the lower limit of quantification (LLOQ);~* No SARS-CoV-2 detected, if not detected.
