  1. Adjusted covariates: Model 0: univariate analysis; Model 1: age and BMI; Model 2: model 1 variables plus race, education and marital status; Model 3: model 2 variables plus hypertension and diabetes mellitus; Model 4: model 3 variables plus smoking status, physical activity status, blood urea nitrogen, creatinine and uric acid
