Positive impact of oral hydroxychloroquine and povidone-iodine throat spray for COVID-19 prophylaxis: an open-label randomized trial
Prophylaxis RCT in Singapore with 3,037 low risk patients, showing lower serious cases, lower symptomatic cases, and lower confirmed cases of COVID-19 with all treatments (ivermectin, HCQ, PVP-I, and Zinc + vitamin C) compared to vitamin C.Meta-analysis of vitamin C in 6 previous trials shows a benefit of 16%, so the actual benefit of ivermectin, HCQ, and PVP-I may be higher. Cluster RCT with 40 clusters.There were no hospitalizations and no deaths. NCT04446104.

risk of COVID-19 severe case, 44.7% lower, RR 0.55, p = 0.05, treatment 42 of 735 (5.7%), control 64 of 619 (10.3%).
risk of COVID-19 case, 31.1% lower, RR 0.69, p = 0.01, treatment 338 of 735 (46.0%), control 433 of 619 (70.0%), adjusted per study, odds ratio converted to relative risk, model 6.
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.

practical, effective, and safe means should be used. Elimination of COVID-19
is a race against viral evolution. No treatment, vaccine, or intervention is
100% available and effective for all current and future variants. Denying the
efficacy of any method increases the risk of COVID-19 becoming endemic; and
increases mortality, morbidity, and collateral damage. We do not provide
