"Adults aged 18-65 years with an FDA emergency use authorized reverse transcription-polymerase chain reaction (RT-PCR) positive for SARS-CoV-2 within 72 hours from swab to the time of enrolment were eligible for participation in this study; Both symptomatic and asymptomatic patients were included given reports finding that both CT values and presence of infectious virus were similar in samples from asymptomatic and symptomatic persons; Symptomatic individuals were eligible given the presence of mild to moderate symptoms without signs of respiratory distress. ;Asymptomatic individuals were eligible if infection was initial diagnosis of SARS-CoV-2 infection
Age ≥ 18 years and ≤ 75 years at the time of the assessment; Able and willing to understand the study, adhere to all study procedures, and provide written informed consent; Diagnosis of COVID-19 disease: If symptomatic, the presence of mild to moderate symptoms without signs of respiratory distress, with FDA-cleared molecular diagnostic assay positive for SARS-CoV-2 within 72 hours from swab to the time of commencing informed consent: If asymptomatic, initial diagnosis of SARS-CoV-2 infection with positive FDA-cleared molecular diagnostic assay obtained no more than 72 hours from initial swab to the time of commencing informed consent.

|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 the preprint article, the study registry and supplementary appendix were used in data extraction and risk of bias assessment. Protocol and statistical analysis plan were not available at the time of data collection. The study achieved the target sample size specified in the trial registry. There is no change from the trial registration in the intervention and control treatments. The primary outcome indicated in the trial registry reflects the primary outcome reported in the paper. All secondary outcomes were added to the trial registration after completion of study recruitment and follow up, and the design was changed from open-label to single-blind.
Quote: "The protocol was amended on June 16th, 2020 after 54 participants were enrolled but before results were available to include adults up to 75 years of age and eliminate exclusion criteria for low white blood cell and lymphocyte count."
On 12th of April, 2021, this study was updated based on the published report.
