CQ vs. neither HCQ or CQ relative risk RR 0.63, p = 0.02
HCQ+AZ or CQ vs. neither relative risk RR 0.65, p = 0.006
risk of death, 32.3% lower, RR 0.68, p = 0.18, treatment 24 of 54 (44.4%), control 42 of 64 (65.6%), NNT 4.7, HCQ+AZ vs. neither HCQ or CQ.
risk of death, 37.1% lower, RR 0.63, p = 0.09, treatment 19 of 46 (41.3%), control 42 of 64 (65.6%), NNT 4.1, CQ vs. neither HCQ or CQ.
