The quartiles of SUA concentration were computed sex, respectively. In male, the cutoff of SUA concentration is <4.47, ≥4.47, ≥5.23, and ≥6.10 mg/dl, respectively, and in female <3.53, ≥3.53, ≥4.15, and ≥4.84 mg/ml, respectively. aAdjusted for the age (continuous), sex (male and female), BMI (continuous) plus smoking (never smoking, quit smoking, and smoking), drinking (never drinking, quit drinking, and drinking), and physical activity (yes/no). In analysis of men and women, adjusted for age (continuous), BMI (continuous), smoking (never smoking, quit smoking, and smoking), drinking (never drinking, quit drinking, and drinking), and physical activity (yes/no). bAdjusted for the same set of variables in model 1 plus prevalence (yes/no) of CHD, hypertension, diabetes, ALT concentration (continuous), Cre concentration (continuous), and FPG concentration (continuous).
