Estimates for association of MeDi components with imaging measures were .05 ≤ P ≤ .1. The model is adjusted for age, sex, education, total energy intakes, BMI, diabetes, hypertension, coronary heart disease, peripheral vascular disease, congestive heart failure, atrial fibrillation, dyslipidemia, stroke, and depressive symptoms.
