RCT in Lebanon showing significantly lower viral load at day 3, and lower hospitalization.
Results are from: 
Raad et al., 1/16/2021, Single Blind Randomized Controlled Trial, Lebanon, Middle East, preprint, 1 author, dosage 200μg/kg single dose.
risk of hospitalization, 85.7% lower, RR 0.14, p = 0.24, treatment 0 of 50 (0.0%), control 3 of 50 (6.0%), continuity correction due to zero event (with reciprocal of the contrasting arm).
risk of viral load, 59.0% lower, RR 0.41, p = 0.01, treatment 50, control 50, percentage relative improvement in Ct value with treatment at day 3.
Effect extraction follows pre-specified rules
prioritizing more serious outcomes. For an individual study the most serious
outcome may have a smaller number of events and lower statistical signficance,
however this provides the strongest evidence for the most serious outcomes
when combining the results of many trials.
