  1. HR (hazard ratios) (95% CI) are shown from Cox proportional hazard models with age as time scale. Models were adjusted for sex, education, and baseline MMSE score. Hypertension and hyperlipidemia were defined as diagnosis of hypertension/hyperlipidemia and treatment with any antihypertensive/lipid-lowering drug. Family history of dementia included at least one affected first-degree relative.
