Fig. 2From: Development and validation of a nomogram model based on pretreatment ultrasound and contrast-enhanced ultrasound to predict the efficacy of neoadjuvant chemotherapy in patients with borderline resectable or locally advanced pancreatic cancerA Nomogram for predicting tumor response (To use the nomogram, an individual patient’s value is located on each variable axis, and a line is drawn upward to determine the number of points received for each variable value. The sum of these numbers is located on the total points axis, and a line is drawn downward to the risk axes to determine the probability of being “responders”) B ROC of the nomogram in the training and validation cohort C Calibration curve of the nomogram in the training cohort D Decision curve analysis for the nomogram. The y-axis measures the net benefit, x-axis indicates threshold probability. The red line represents the net benefit of the predictive nomogramBack to article page
