The 3-, 5-, and 8-year nomograms predicting the OS of ccRCC patients were established based on age, histologic grade, pathologic stage, and NOP2 expression level (Supplementary Fig. S1F, G), according to the results of the multivariable Cox regression analysis in the TCGA-KIRC cohort. Here, NOP2 is linked to nonpapillary renal cell carcinoma.
