*

P for the full population were calculated across all six A1C and diabetic groups ordered from lowest to highest as follows: no diabetes and lowest to highest quartile of A1C, diabetes and A1C <7%, and diabetes and A1C ≥7%.

Adjusted for age, race/ethnicity, sex, systolic blood pressure, current and former cigarette smoking, alcohol consumption, physical activity, waist circumference, chronic kidney disease, total cholesterol, and C-reactive protein. ref., reference category.
