¹Duplicate test results.

Data were expressed as n (percentage) or mean ± SD. Comparisons were performed using the Student’s t-test, Pearson’s chi-squared test, and Fisher’s exact test. ALP: Alkaline phosphatase; ALT: Alanine aminotransferase; AST: Aspartate aminotransferase; CA19-9: Carbohydrate antigen 19-9; CEA: Carcinoembryonic antigen; GB: Gallbladder; GBEF: Gallbladder ejection fraction; GGT: Gamma (γ)-gamma-glutamyl transferase.
