ALT, alanine aminotransferase, AST, aspartate aminotransferase; BMI, body mass index; GGT, gamma-glutamyl transferase; HDL-C, high-density lipoprotein cholesterol; HOMA-IR, homeostasis model assessment of insulin resistance; LDL-C, low-density lipoprotein cholesterol; NAFLD, non-alcoholic fatty liver disease; NS, non-significant; TNFα, tumor necrosis factor-α. Data are expressed as means ± standard deviation.
P value: the chi-square test for non-continuous variables and the unpaired Student’s two-tailed t-test or nonparametric Mann-Whitney U test, as appropriate, for continuous variables.
