  1. IFG: impaired fasting glucose; IGT: impaired glucose tolerant; IFSG: impaired fasting and stimulated plasma glucose; NGT: normal glucose tolerance; HOMA-IR: homeostasis model assessment-insulin resistance; QUICKI: quantitative insulin sensitivity check index.
  2. †P was calculated using Kruskal-Wallis test and the multiple comparison was conducted by Dunnett-t test.
  3. *The difference was significant when compared with NGT group.
