An ROC curve of the blood‐bile glucose difference, bile sodium, and bile pH as a predictor for the development of cholangiopathy. A blood‐bile glucose difference of <6.5 mmol/L has 83% sensitivity and 62% specificity for predicting cholangiopathy (AUROC, 0.80; P = 0.001). No such cutoff value can be made from the bile sodium and bile pH. The AUROC (95% CI)s were 0.80 (0.68‐0.91; P = 0.001) for the blood‐bile glucose difference; 0.71 (0.53‐0.89; P = 0.02) for bile sodium; and 0.64 (0.48‐0.79; P = 0.12) for bile pH.
