We conducted survival analysis using GEO data with R language software and TCGA data in Oncolnc database to demonstrate the association between the expression of significant hub genes and overall survival time. CDC20 showed a statistical significance in both the databases (P=0.001 in GEO; P=0.0361 in Oncolnc), while CDCA8 only showed a statistical significance in GEO (P<0.001 in GEO; P=0.277 in Oncolnc).
