Fig. 4From: Clinical-MRI radiomics enables the prediction of preoperative cerebral spinal fluid dissemination in children with medulloblastomaROC curves of the traditional feature model and nomogram. a The AUC was significantly different (0.67 and 0.89, respectively) between the clinical model and the nomogram in the training cohort. b, c The AUC of the nomogram was significantly higher than a clinical model in the internal and external cohorts. Delong’s test showed that the differences between the ROC curves of the nomogram and clinical model were significantly different in both the training and two validation cohorts.
