Bedside score predicting retained common bile duct stone in acute biliary pancreatitis

Figure 1 Receiver operating characteristic curve analysis for age, gamma-glutamyltransferase level and dilated common bile duct on multivariate regression analysis. AUC: Area under the curve.

Figure 2 Receiver operating characteristic curve analysis of the score developed [0. 5 × age + 0.02 × gamma-glutamyltransferase (U/L) + 10 × common bile duct width by ultrasound]. AUC: Area under the curve.
