We performed a survival analysis of 75 CN-AML patients from the TCGA database and found that EFS (P = 0.00016, Log-rank test, Fig. 1) and OS (P < 0.0001, Log-rank test, Fig. 1) were significantly lower in the high expression level of PDE7B group than in the low level PDE7B group. Here, PDE7B is linked to acute myeloid leukemia.
