Values are presented as number (%) or mean±standard deviation.
HbA1c, hemoglobin A1c; LDL, low density lipoprotein; HDL, high density lipoprotein; AST, aspartate aminotransferase; ALT, alanine aminotransferase; γ-GT, gamma-glutamyl transpeptidase.
P-values were calculated by one way ANOVA test or chi-square test.
