Data are shown as the median and interquartile range (IQR) or percentages. values were from analysis of the Kruskal-Wallis test or Pearson’s test. A two-tailed value of less than 0.05 was considered statistically significant. NAFLD: nonalcoholic fatty liver disease; BMI: body mass index; ALT: alanine aminotransferase; AST: aspartate aminotransferase; ALP: alkaline phosphatase; γ-GT: γ-glutamyl transpeptidase; TBA: total bile acids; GCA: glycocholic acid; BUN: blood urea nitrogen; FBG: fasting blood glucose; LDL-C: low-density lipoprotein cholesterol; HDL-C: high-density lipoprotein cholesterol; Q1: the GCA-to-TBA ; Q2: the GCA-to-TBA ratio 0.75-1.00; Q3: the GCA-to-TBA ratio 1.00-1.34; Q4: the GCA-to-TBA .
