Abbreviations: CI confidence interval, aHRs adjusted hazard ratios; other abbreviations as in Table 1. The above model adjusted for sex, age, GGT, ALB, GLB, TB, DBIL, SBP, DBP, ALP, BUN, CR, UA, FPG, TG, HDL-C, LDL-C, Height and BMI. Note: In each case, the model is not adjusted for the stratification variable
