In additional analyses performed after propensity score matching of patients in the ATM (n = 72) and no modification (n = 72) groups, rates of ischemic event and ischemic stroke remained significantly lower in the ATM group (hazard ratio, 0.69; 95% CI, 0.57–0.94; P = 0.02, and hazard ratio, 0.67; 95% CI, 0.62–0.97; P = 0.03, respectively). The gene discussed is ATM; the disease is ischemic stroke.
