The results of DSS data analysis showed that in GBM (P = 0.004), HNSC (P = 0.007), KICH (P = 0.005), KIRC (P = 0.002), KIRP (P < 0.001), and LGG (P < 0.001) patients, the high expression of PDIA3 was correlated with poor outcomes, and UVM (P = 0.002) patients (Figure 4(a)), especially KICH (hazard ratio = 1.01). This evidence concerns the gene PDIA3 and glioblastoma.
