  • Data are means ± SD or n (%). P values for overall comparison between five categories of glucose tolerance are shown (ANOVA for continuous variables, χ2 test for categorical variables). Bonferroni post hoc tests (continuous variables): all pairwise comparisons between categories of glucose tolerance were significant at P < 0.05, except for those marked as follows:

  • *P > 0.05 vs. isolated IGT;

  • P > 0.05 vs. IFG + IGT;

  • P > 0.05 vs. isolated IFG;

  • §P > 0.05 vs. NGT.
