Prospective study of 9,212 autoimmune rheumatic disease patients showing lower mortality with HCQ, without reaching statistical significance. Authors incorrectly state "HCQ use did not influence occurrence of COVID-19 (RR = 0.909, CI (0.715,1.154), p = 0.432) or mortality (p = 0.097)" [nature.com]. CFR for the autoimmune rheumatic disease patients was 4.6 times higher than in the general population from the same area.
risk of death, 65.9% lower, RR 0.34, p = 0.10, treatment 5,266, control 3,946.
risk of case, 9.1% lower, RR 0.91, p = 0.43, treatment 167 of 5,266 (3.2%), control 147 of 3,946 (3.7%), NNT 181, adjusted per study.
