Model 1 was unadjusted.

Model 2 was adjusted for age.

Model 3 was adjusted for age, sex and BMI.

Model 4 was adjusted for age, sex, BMI, current smoking, current drinking, family history of diabetes, creatinine, GGT, FPG, insulin, LDL-C and TG.

Model 5 was adjusted for age, sex, BMI, current smoking, current drinking, family history of diabetes, creatinine, GGT, FPG, insulin, LDL-C, TG, baseline SBP and DBP.

BMI, body mass index; DBP, diastolic blood pressure; FPG, fasting plasma glucose; GGT, glutamyltransferase; HTN, hypertension; LDL-C, low-density lipoprotein cholesterol; SBP, systolic blood pressure; TG, triglycerides.
