Retrospective 1,106 prostate cancer patients, showing higher mortality with HCQ treatment.
risk of death, 333.0% higher, OR 4.33, p < 0.001, treatment 70, control 407, adjusted per study, propensity score matching, multivariable, RR approximated with OR, excluded in exclusion analyses: confounding by indication is likely and adjustments do not consider COVID-19 severity at baseline.
