Table 2. Parameters of β-cell function, insulin resistance (or insulin sensitivity) and β-cell function adjusted by insulin resistance.

Values are presented as mean±standard deviation. P values were calculated after normalizing log transformation using one-way analysis of variance.

NGT, normal glucose tolerance; IGT, impaired glucose tolerance; HOMA-β, homeostasis model assessment of pancreatic β-cell; HOMA-IR, homeostasis model assessment of insulin resistance; ISSI-2, insulin secretion-sensitivity index-2.

^aSex and body mass index (BMI) adjusted P values were calculated after normalizing log transformation using analysis of covariance with age and BMI as covariates, ^b,c,dThe data with different superscript letters are significantly different (P<0.05) according to the Games-Howell post hoc test.
