VKORC1 and Stroke: We calculated the OR for the variables that were significantly more frequent in the stroke group: smoking (3.222 (95%CI 2.031; 5.113), P < .001), AH (1.657 (95%CI 1.144; 2.400), P = .008), history of MI (3.552 (95%CI 1.401; 9.001), P = .008), LDL-C > 77 mg/dL (2.207 (95%CI 1.413; 3.447), P = .001), carotid plaque (2.279 (95%CI 1.591; 3.264), P < .001), VKORC1 (−1639G > A) polymorphism w/m or m/m genotype (1.587 (95%CI 1.084; 2.324), P = .01).
