Nomogram for predicting chylous ascites after right colectomy

Figure 3 Validation of the nomogram. A: receiver operating characteristic (ROC) curve for the nomogram. C statistic/ area under the receiver operating characteristic curve (AUC) = 0.770 (95%Cl: 0.706-0.834); B: Nomogram calibration curve. The y-axis represents the actual probability of chylous ascites. The x-axis represents estimated probability. The ideal line represents a perfect prediction model. The apparent line represents the performance of the nomogram, and a close fit to the ideal line represents a good prediction.
