Model 1: no covariates were adjusted. Model 2: age, sex, and race/ethnicity were adjusted. Model 3: age, sex, race/ethnicity, education level, the ratio of family income to poverty, BMI, energy intake, protein intake, carbohydrate intake, dietary fiber intake, total fat intake, LDL-C, HDL-C, TG, TCHO, urine albumin, urine creatinine, albumin creatinine ratio, HbA1c, SBP, DBP, heavy alcohol consumption, smoking status, and minutes sedentary activity were adjusted. In the subgroup analysis stratified by sex, age, and race/ethnicity, the model is not adjusted for sex, age, and race/ethnicity, respectively.
