Verification of the column chart
To validate the column chart model as a useful tool for predicting the prognosis of BPS/IC, we conducted an analysis using the validation cohort consisting of 302 people. ROC curve analysis showed that the model exhibited considerable discriminative ability. The AUC values obtained were 0.965(0.932–0.100), 0.619(0.550–0.687), 0.684(0.604–0.764), 0.906(0.855–0.957), 0.779(0.706–0.852), and 0.805(0.744–0.866), for nomogram, age, CD117, P2X3R, NGF, and TrkA, respectively, indicating that the presence of these factors offers clinical value as prognostic indicators (Fig. Verification of the ROC curve
