Data are expressed as mean±SD. P values were calculated using a paired t-test between the values recorded at the baseline and after treatment.
*P values were calculated using Student’s t-test for delta changes between the two groups.
†Log-transformed values were used for comparison.
ALT, alanine aminotransferase; AST, aspartate aminotransferase; AUC, area under the curve; DBP, diastolic blood pressure; HDL, high-density lipoprotein; HOMA-β, homeostasis model assessment of β-cell function; HOMA-IR, homeostasis model assessment of insulin resistance; IGI, insulinogenic index; LDL, low-density lipoprotein; NS, not significant; QUICKI, quantitative insulin sensitivity check index; SBP, systolic blood pressure.
