In addition, the receiver operating characteristic (ROC) curve was used to analyze the diagnostic value of the CDCA7 gene in gliomas and revealed that within 1, 3, and 5 years, the CDCA7 area under the curve (AUC) (Figure 4C) was 0.693, 0.732, and 0.702, respectively, using data from the TCGA datasets, while in the CGGA dataset, the CDCA7 AUC (Figure 4D) was 0.610, 0.676, and 0.703, respectively, indicating that the expression level of CDCA7 has good diagnostic value for gliomas. Here, CDCA7 is linked to central nervous system cancer.
