dysfunction or failure;

Definition of Standard care: Oseltamivir 75 mg 12 hourly for 10 days and hydroxychloroquine 400 mg 12 hourly on day-one followed by 200 mg 12 hourly daily on day-2 to 10 days conforming to the national standard of care therapy.

Achievement of two successive negative SARS-CoV-2 PCR analysis tests 48 hours apart by nasopharyngeal swab, normalization of body temperature for 48 hours, improvement of radiological abnormalities at day 14 and discharge rate out of the hospital
|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 pre-print article, the study registry was used in data extraction and assessment of risk of bias.
National standard of care therapy consisted of oseltamivir 75 mg 12 hourly for 10 days and hydroxychloroquine 400 mg 12 hourly on day-one followed by 200 mg 12 hourly daily on day-2 to 10 days.
The study achieved the proposed sample size. There were no differences between the trial registration and the study report in treatments. One primary outcome stated in the report (discharge out of hospital) was not specified in the trial registration. Also, 'Improvement of radiological abnormalities' was specified as a secondary outcome in the registry but a primary outcome in the report, while the secondary outcomes, 'normalization of C-reactive protein (CRP) and serum ferritin levels', were not specified in the registry.
