AGR was entered as a continuous variable per change 0.1 unit.
Adjusted for age, gender, race, education, marital status, poverty-to-income ratio, body mass index, drinking, smoking, physical activity, hypertension, diabetes, coronary heart disease, stroke, and depression. Only 97.5% of the data is presented.
