The results of the Cox proportional hazards model showed that the expression of PDE4DIP was significantly correlated with lower OS in patients with LAML (p = 0.001), PCPG (p = 0.020), thymoma (THYM) (p = 0.002), and UVM (p = 0.003) (Figure 3a). The gene discussed is PDE4DIP; the disease is thymoma.
