Model 1 adjusted for age and sex; Model 2 adjusted for age, sex, vascular risk factors (hypertension, diabetes mellitus, hyperlipidemia, cigarette smoking and chronic kidney disease); Model 3 adjusted for age, sex, vascular risk factors, white matter hyperintensities and lacunes; Model 4 adjusted for age, sex, vascular risk factors, white matter hyperintensities, lacunes and diastolic blood pressure; Model 5 adjusted for age, sex, vascular risk factors, white matter hyperintensities, lacunes and pulse pressure.

CMB, cerebral microbleeds; DI, deep or infratentorial; SL, strictly lobar.
