Cox proportional risk regression model showed that PDIA3 expression in ACC (P = 0.011), CESC (P = 0.006), GBM (P = 0.003), HNSC (P = 0.004), KICH (P = 0.003), KIRP (P = 0.001), LAML (P = 0.022), LGG (P < 0.001), UCEC (P = 0.05), and UVM (P = 0.002) was associated with OS of tumor patients (Figure 3(a)). Here, PDIA3 is linked to glioblastoma.
