PDE7B and acute myeloid leukemia: By comparing the EFS (HR: 4.8206, 95% CI: 1.9815–11.7273, P = 0.0005, Cox regression analysis, Table 1) and OS (HR: 4.2915, 95% CI: 1.7509–10.5182, P = 0.00145, Cox regression analysis, Table 1) between the PDE7B high expression group and PDE7B low expression group, it was showed that the PDE7B gene is an independent and unfavorable prognostic factor for CN-AML patients.
