Data are presented as mean ± standard deviation or median (interquartile range). N. Kruskal Wallis test for continuous variables and χ2 test for categorical variables were applied to assess the differences among three groups.
NGT normal glucose tolerance, T2DM type 2 diabetes mellitus, BMI body mass index, HbA1c glycated hemoglobin A1c, FPG fasting plasma glucose, PG30 30 min plasma glucose, PG2H 2 h plasma glucose.
