Small prophylaxis trial with 29 low dose HCQ and 455 control healthcare workers in India, showing no statistically significant differences.
risk of hospitalization, 94.8% lower, RR 0.05, p = 0.61, treatment 0 of 29 (0.0%), control 17 of 455 (3.7%), NNT 27, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm).
relative severity, 26.9% better, RR 0.73, p = 0.21, treatment 29, control 455.
risk of case, 4.6% higher, RR 1.05, p = 0.81, treatment 6 of 29 (20.7%), control 90 of 455 (19.8%).
Effect extraction follows pre-specified rules prioritizing more serious outcomes.
