Outcomes
Our primary outcome measure was the recovery delay defined as the period between the day of the 14th RT-PCR-positive result and the day of the second successive negative RT-PCR test result. Secondary outcomes included the monitoring for the SARS-CoV-2 RT-PCR cycle threshold (Ct) values from the date of randomization until the second successive negative RT-PCR test result. Ct value is inversely correlated to the level of viral ribonucleic acid (RNA) in RT-PCR tests for SARS-CoV-2 [
