**2.6 Survival analysis**

The overall survival (OS) and disease-free survival (DFS) of the target genes were analyzed by Gene Expression Profiling Interactive Analysis V.2 database (GEPIA2; http://gepia2.cancer-pku.cn/), which is an online tool used for the visualization, evaluation, and download of large-scale cancer-related genomics datasets. We

utilized this tool to generate a survival map that screened the prognostic value of the hub genes we selected in various cancers. "0.05" as the significance level, and "median" as the group cutoff.
