Abbreviations: MRI, magnetic resonance imaging; NAFLD, nonalcoholic fatty liver disease.
Expressed as SD increment of age and age-squared adjusted residuals.
Model 1 is adjusted for age at MRI, age-squared at MRI, sex, alcohol (drinks per week), years between computed tomographic scan and covariate assessment, and years between computed tomographic scan and MRI. Model 2 is adjusted for model 1 covariates plus visceral adipose tissue, body mass index, and menopausal status. Model 3 is adjusted for model 2 covariates plus systolic blood pressure, hypertension, levels for high-density lipoprotein cholesterol and low-density lipoprotein cholesterol, lipid treatment, current smoking, diabetes, history of cardiovascular disease, physical activity index, homeostatic model assessment of insulin resistance, and levels for C-reactive protein and homocysteine.
Expressed as percentage of total cranial volume.
Covert brain infarct models are not adjusted for menopausal status, owing to the lack of covert brain infarcts occurring in nonmenopausal women.
