Recursive partitioning of 217 patients for the presence of persisting bile leak and other pathology on repeat ERCP (Pathology) or the absence of both (No pathology). Rule sensitivity, 94% (95% CI, 83%-99%); specificity, 24% (95% CI, 18%-31%); positive predictive value, 26% (95% CI, 20%-34%); and negative predictive value, 93% (95% CI, 81%-99%). ALP, alkaline phosphatase.
