Model 1: Adjusted for age, age2, sex, race-ethnicity, education and medical health insurance status.
Model 2: Adjusted for age, age2, sex, race-ethnicity, education and health insurance status, smoking, moderate alcohol intake, physical activity, BMI, hypertension, diabetes, hypercholesterolemia, history of heart disease.
Model 3: Full model: including all covariates in Model 2 and WMHV, CPF, SBI and APOE genotype.
