Nomogram construction. A nomogram predicted the survival possibility of gliomas in the training set (a). Calibration plot for the nomogram demonstrated the observed and predicted OS probabilities were highly consistent (b-d). ROC curve assessed the prognosis prediction accuracy of the nomogram at 1-, 3- and 5-year overall survival (e-g). Abbreviations: OS, overall survival; AUC, area under curve
