  • Data are RR (95% CI). Subjects without diabetes were adopted as the reference group. Analyses were adjusted for age, education, ε4 status, diabetes medication, midlife systolic blood pressure, cholesterol, BMI, ABI, and stroke. AD definition includes subjects with concomitant CVD contributing to dementia.
