P‐values by Spearman's rank correlation. Between‐group comparisons were tested by unpaired Mann–Whitney U‐test or χ2‐test. One‐way anova and Games–Howell test were used to compare the four groups. AOC, area over the blood concentration‐time curve; eGFR, estimated glomerular filtration rate; HbA1c, glycated hemoglobin.
