Prognostic Nomogram for Gastrointestinal Stromal Tumors after Surgery Based on the SEER Database

Figure 4

AUC values of ROCs for the nomogram and M-NIH classifications. (a, b) Training group: three-year GSS (80.4% vs. 70.6%) and five-year GSS (78.8% vs. 70.9%). (c, d) Validation group: three-year GSS (81.8% vs. 71.6%) and five-year GSS (81.4% vs. 73.6%). AUC: area under the ROC; GISTs: gastrointestinal stromal tumors; M-NIH classification: modified NIH classification; ROC curve: receiver operating characteristic curve.
