As shown in the Fig. 2D, the AUCs of the ROC curves for predicting the 1-year, 3-year, and 5-year survival outcomes of glioma patients in the TCGA and CGGA databases were all greater than or close to 0.7, suggesting that KIF4A expression can be used to predict glioma patient survival. Here, KIF4A is linked to central nervous system cancer.
