A Nomogram for preoperative prediction of CR-POPF following DP. Points indicate BMI, preoperative serum albumin level, pancreatic thickness and pancreatic texture. The score for each value was assigned by drawing a line upwards to the “Points” line, and the sum of the four scores was plotted on the “Total points” line (probability of CR-POPF). B Receiver operating characteristic (ROC) curves were used to evaluate the nomogram model performance. C The calibration curve of the nomogram model
