The univariate analysis showed that KAF (OR 8.57, 95% CI 1.15–65.05, p = 0.036) and (re)-initiation of oral anticoagulant after stroke (OR 0.08, 95% CI 0.02–0.25, p < 0.001) were significantly correlated with outcome of death after the index event. The gene discussed is CFI; the disease is stroke disorder.
