A The calibration curve of the T2WI radiomic-clinical nomogram in the validation cohort. The dotted line means the optimal probability prediction model, while the solid line represents the real scenario. An acceptable error occurred because of the imbalanced data. B DCA for clinical-radiological signature (red line), T2WI radiomics signature (blue line) and T2WI radiomic-clinical nomogram (purple line). The “All” line is made with the assumption that all patients have poor prognosis. The curve indicates that the net benefit of the nomogram is better than the other models when the threshold is in the range between 0.1 and 0.8. C The T2WI radiomic-clinical nomogram incorporated three factors of rad-score, age and FIGO staging
