  • Data are median (n). Model 1: adjusted for age; model 2: adjusted for age, BMI, smoking, alcohol consumption, physical activity, aspirin use, HbA1c, and history of hypertension or hypercholesterolemia; model 3: in addition to the variables adjusted in model 2, further adjusted for the dietary factors (total energy intake, glycemic load and fibers) that were not examined as the primary independent variable; model 4: in addition to variables adjusted in model 3, further adjusted for magnesium.
