Imaging-independent model for predicting choledocholithiasis in acute biliary pancreatitis

Figure 3 Comparison of decision rules. A: Mosaic diagram in which each field’s size corresponds to the number of correct and false rule-in and rule-out classifications (i.e., the four cells of the respective contingency tables). False rule-outs in red signify missed CDL, and correct rule-outs in yellow correspond to true negatives for CDL; B: Two receiver operating characteristic (ROC) curves were plotted for the random forest model and the common bile duct diameter; C: ROC curve for our predictive model. CDL: Choledocholithiasis; AUC: Area under the curve; CI: Confidence interval; FPR: False positive rate; CBD: Common bile duct; GTE: Greater than or equal to.
