Population attributable risks of presumed etiological factors for which data were available only for subgroups, for any stroke (n/N = 545/3,570).

Category boundaries for C-reactive protein quartiles were 0.896, 1.900, and 3.960 for men and 0.902, 1.830, and 3.360 for women. Category boundaries for carotid IMT quartiles were 0.72, 0.80, and 0.92 for men and 0.67, 0.76, and 0.85 for women.aAll analyses are adjusted for age, sex, hypertension, smoking, diabetes mellitus, atrial fibrillation, coronary disease, and overweight/obesity, if appropriate.bTotal PAR based on hypertension, smoking, diabetes mellitus, atrial fibrillation, coronary disease, and overweight/obesity, calculated in this subgroup of the study population.n.a., not applicable because the hazard ratio is smaller than one.
