Values are expressed as means (standard deviation). TG was described by median and inter-quartile range.

Abbreviations: NWNT, normal waist normal triglyceride; HTG, hypertriglyceridemia; EW, enlarged waist circumference; HTGW, hypertriglyceridemic-waist; BMI, body mass index; WC, waist circumference; SBP, systolic blood pressure; DBP, diastolic blood pressure; TC, total cholesterol; LDL-C, low density lipoprotein-cholesterol; HDL-C, high density lipoprotein-cholesterol; TG, triglyceride; FPG, fasting plasma glucose.

a Comparison among four groups.

b NS = no significant, P value >0.05.

# Compared with NWNT group, P <0.05.

& Compared with HTG group, P <0.05.

$ Compared with EW group, P <0.05.

Note: NWNT was defined as serum triglyceride concentration <1.7 mmol/L and waist circumference <90 cm for men and <80 cm for women; HTG was defined as serum triglyceride concentration ≥1.7 mmol/L and waist circumference <90 cm for men and <80 cm for women; EW was defined as serum triglyceride concentration <1.7 mmol/L and waist circumference ≥ 90 cm for men and ≥ 80 cm for women; HTGW was defined as serum triglyceride concentration ≥1.7 mmol/L and waist circumference ≥ 90 cm for men and ≥ 80 cm for women.
