Abbreviations: 2hPG, 2-h post-OGTT plasma glucose; BMI, body mass index; CRP, C reactive protein; DBP, diastolic blood pressure; HDL-c, high-density lipoprotein cholesterol; HOMA-IR, homeostasis model assessment-insulin resistance; LDL-c, low-density lipoprotein cholesterol; SBP, systolic blood pressure; SFA, subcutaneous fat area; VFA, visceral fat area; W, waist circumference.

Variables included in the original models are obesity indices (Model 1: BMI, W, % fat, VFA and SFA; Model 2: BMI and W; Model 3: % fat, VFA and SFA) and basic CVD risk factors, including age, smoking status, SBP, DBP, HOMA-IR, 2hPG, LDL-c, HDL-c, CRP, anti-hypertensive therapy, anti-diabetic therapy and lipid-lowering therapy. For women we also adjusted the menopausal status.
