Diagnostic performance of γ-GT, clay stool, and GCDCA/CDCA compared to the combination of three variables in the derivation cohort.The areas under receiver operating characteristic curve (AUC) for γ-GT, clay stool, and GCDCA/CDCA were 0.77, 0.73, and 0.79, and for γ-GT, clay stool, and GCDCA/CDCA was 0.89. P values show the AUC for combination variables versus the AUC for each individual variable
