Multivariate analysis of factors related to EFS included age (≥ 60 vs. < 60 years), AML types (Non-M3 vs. M3), risk group (high vs. inter vs. low-risk), the time-dependent variable for allo-HSCT (yes vs.no), number of co-mutations (≥ 3 vs. < 3), IDH2 (mutated vs. wild type), RUNX1 (mutated vs. wild type) and U2AF1 (mutated vs. wild type). Here, U2AF1 is linked to acute myeloid leukemia.
