Random allocation using the block randomisation method was performed in all four branches of the strata, based on two prognostic factors such as age (< 55 and ≥55) and disease severity based on O2 saturation (<85 and ≥85). The patient, assessor, and analyser in the two groups did not have access to the randomisation list and type of administered drug (Triple blind).
