Primary Outcome Measures
NameTimeMethod
Time to Hospital Discharge or "Ready for Discharge" up to Day 28Up to Day 28

Defined as days from randomization to hospital discharge or "Ready for Discharge" not followed by ordinal scale category \>1, hospital readmission or death. Hospital discharge or "Ready for Discharge" is defined as an ordinal score of 1 on the 7-point ordinal scale. Participants who die are censored at Day 28.

1. Discharged (or "ready for discharge" as evidenced by normal temperature and respiratory rate, and stable oxygen saturation on ambient air or \</= 2L supplemental oxygen)

2. Non-intensive care unit (ICU) hospital ward (or "ready for hospital ward") not requiring supplemental oxygen

3. Non-ICU hospital ward (or "ready for hospital ward") requiring supplemental oxygen

4. ICU or non-ICU hospital ward, requiring non-invasive ventilation or high-flow oxygen

5. ICU, requiring intubation and mechanical ventilation
