Model 1: adjusted for age, sex, high school completion, race-ethnicity, total calories, Mediterranean diet score, moderate alcohol use, moderate-heavy physical activity, smoking, sodium consumption
Model 2: variables in model 1+ estimated glomerular filtration rate, body mass index, hypertension, hypercholesterolemia, diabetes
