Prospective study of healthcare workers in Uzbekistan showing lower mortality and cases with quercetin prophylaxis. Very minimal details are provided, there is no baseline information, and control mortality is very high. This study is excluded in meta analysis: minimal information, no baseline details, very high control mortality without explanation.
risk of death, 96.4% lower, RR 0.04, p < 0.001, treatment 0 of 70 (0.0%), control 6 of 20 (30.0%), NNT 3.3, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm).
risk of symptomatic case, 98.5% lower, RR 0.02, p < 0.001, treatment 1 of 70 (1.4%), control 19 of 20 (95.0%), NNT 1.1.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates
