  1. Results are expressed in mean ± standard deviation
  2. CEA aspartate aminotransferase, CA19–9 alanine aminotransferase, AST aspartate aminotransferase, ALT alanine aminotransferase, HDL high-density lipoprotein, LDL low-density lipoprotein, TG triglyceride
  3. aIn the case of bile acids, the sample did not have a normal distribution, thus a non-parametric test was performed using the Mann-Whitney test
