Values are means ± SD. HOMA-IR: homeostasis model assessment-insulin resistance; HOMA-β: homeostasis model assessment for β-cell function; QUICKI: quantitative insulin sensitivity check index; AUC: area under the curve. The values for each index with different superscript letters are statistically different at by comparing different patterns of each time, as determined by Dunn’s multiple comparison test.
