Consumption of alcohol (g/week)	1.0 (55.0)
Smoking^†
Current-smoker	3134 (22.2%)
Past-smoker	2261 (16.1%)
Never-smoker	8691 (61.7%)
Regular exerciser^†	2447 (17.4%)
Fasting plasma glucose (mmol/L)	5.1 (0.6)
Hemoglobin A1c (NGSP) (%)	5.1 (0.5)
Triglycerides (mmol/L)	0.7 (0.5)
Total cholesterol (mmol/L)	5.0 (1.1)
HDL cholesterol (mmol/L)	1.5 (0.5)
Aspartate aminotransferase (IU/L)	17.0 (7.0)
Alanine aminotransferase (IU/L)	15.0 (8.0)
Gamma-glutamyltransferase (IU/L)	13.0 (9.0)
Diabetes mellitus^†	148 (1.1%)
SBP (mmHg)	111.5 (19.0)
DBP (mmHg)	69.5 (12.5)
TyG-index	8.0 (0.8)

The TyG-index was calculated by the following formula: TyG = Ln [TG (mg/dl) × FPG (mg/dl)/2]. Diabetes mellitus: HbA1c ≥ 6.5% or fasting plasma glucose ≥126 mg/dl or getting treatment for diabetes. Continuous variables are presented as median (interquartile range).
