Identification of prognostic genes, construction and validation of the prognostic model. A The forest plot showed the relationship between the gene expression and OS. Kaplan–Meier survival analysis of patients in the high or low-risk group in the B TARGET, C GSE49711, and D E-MTAB-8248 datasets. The independent prognostic factors in the E-MTAB-8248 dataset was assessed by E univariate and F multivariate Cox analysis. G TIDE, dysfunction, MSI and exclusion score in the high and low-risk groups. H–J ROC curves for predicting survival at 3, 5, and 10 years of NBL patients in our model, the E-MTAB-8248, and the GSE49711 datasets, respectively. K Multivariable ROC curve compared with the TIDE and TIS risk models. p-value < 0.05 was considered significant
