Planned RCT of HCQ vs. HCQ+nitazoxanide which was aborted due to the retracted Surgisphere paper. Authors retrospectively analyze a small set of HCQ vs. nitazoxanide patients (which were protocol deviations in the planned RCT), showing reduced hospitalization time and ICU admission with nitazoxanide.
risk of death, 68.2% lower, RR 0.32, p = 0.38, treatment 1 of 17 (5.9%), control 5 of 27 (18.5%), NNT 7.9.
risk of mechanical ventilation, 86.7% lower, RR 0.13, p = 0.15, treatment 0 of 17 (0.0%), control 4 of 27 (14.8%), NNT 6.8, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm).
risk of ICU admission, 59.3% lower, RR 0.41, p < 0.001, treatment 0 of 17 (0.0%), control 16 of 27 (59.3%), NNT 1.7, adjusted per study.
hospitalization time, 51.8% lower, relative time 0.48, p = 0.006, treatment 17, control 27.
