  1. Data are median (interquartile range). FPG, fasting plasma glucose; FPI, fasting plasma insulin; HOMA-IR, homeostasis model assessment of insulin resistance; HOMA-β, homeostasis model assessment of β-cell function; NTNW, normal triglycerides (TG) level and normal waist circumference (WC); NTGW, normal TG level and enlarged WC; HTNW, elevated TG level and normal WC; HTGW, elevated TG level and enlarged WC. *Kruskal-Wallis test among NTNW, NTGW/HTNW, and HTGW.
