RR, relative risk; CI, confidence interval; WC, waist circumference.

Model 1: no adjustment.

Model 2: adjusted for age, sex, smoking, and alcohol drinking at baseline.

Model 3: adjusted for the variables in model 2 plus ALT, TG, HDL-C, BMI, and systolic BP at baseline.

Model 4: adjusted for the variables in model 3 plus HbA1c at baseline.
