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, 214.8% higher, RR 3.15, p = 0.38, treatment 5 of 27 (18.5%), control 1 of 17 (5.9%).
risk of mechanical ventilation, 651.9% higher, RR 7.52, p = 0.15, treatment 4 of 27 (14.8%), control 0 of 17 (0.0%), continuity correction due to zero event (with reciprocal of the contrasting arm).
risk of ICU admission, 145.5% higher, RR 2.45, p < 0.001, treatment 16 of 27 (59.3%), control 0 of 17 (0.0%), adjusted per study.
hospitalization time, 107.4% higher, relative time 2.07, p = 0.006, treatment 27, control 17.
