The results showed that P4HA3 was a risk factor for OS in UVM, UCEC, THCA, STAD, PAAD, KIRP, KIRC, kidney chromophobe (KICH), GBM, COAD, cervical squamous cell carcinoma (CESC), and BLCA (Figure 4A); P4HA3 was a risk factor for DSS in UVM, PAAD, mesothelioma (MESO), LUAD, LGG, KIRP, KIRC, KICH, GBM, COAD, CESC, BRCA, BLCA, and adrenocortical carcinoma (ACC) (Figure 4B); P4HA3 was a risk factor for DFI in UVM, UCEC, THCA, PAAD, KIRP, KIRC, KICH, GBM, COAD, CESC, BRCA, and BLCA (Figure 4C); P4HA3 was a risk for PFI in PAAD, KIRP, and CESC (Figure 4D). The gene discussed is P4HA3; the disease is glioblastoma.
