The numerous treatment regimens (induction: P = 0.475, Fisher’s exact test, Supplementary Table 1; transplant: P = 0.717, Fisher’s exact test, Supplementary Table 1; before transplant: P = 0.719, Fisher’s exact test, Supplementary Table 1) and relapse (P = 0.473, Fisher’s exact test, Supplementary Table 1) of AML were not significantly associated with PDE7B expression levels. This evidence concerns the gene PDE7B and acute myeloid leukemia.
