^*Model 1 adjusts for total energy intake, age, sex, and race

^†Model 2 adjusts for Model 1 plus other socio-demographic factors such as geographic region, annual family income (< vs. ≥ $20,000/year), educational achievement (< vs. ≥ high school diploma), health insurance, marital status, cigarette smoking, alcohol consumption, physical activity

^‡Model 3 adjusts for Model 2 plus potentially-mediating physiologic parameters such as systolic blood pressure, diastolic blood pressure, body mass index, high-density lipoprotein cholesterol, total cholesterol, triglycerides, estimated glomerular filtration rate, natural log-transformed C-reactive protein, urine albumin-to-creatinine ratio, diabetes, history of coronary heart disease, history of atrial fibrillation, and left ventricular hypertrophy
