EKLF expression was associated with secondary AML (primary/secondary) (HR 10.71; 95%CI 1.54-74.49, P = 0.02), GATA2 expression (no/yes) (HR 5.45; 95% CI 1.5-19.68, P = 0.009), and cMPL expression (no/yes) (HR 5.16; 95%CI 1.51-23.08, P = 0.03). This evidence concerns the gene KLF1 and acute myeloid leukemia.
