WT1 and acute myeloid leukemia: In the TARGET-AML training cohort, after incorporating the aforementioned common clinical characteristics and risk scores, regression analyses and PH assumption tests identified risk score (p < 0.05, HR = 2.022, 95% CI = 1.331–3.071) and WT1 mutation (p < 0.05, HR = 3.598, 95% CI = 1.402–9.234) as independent prognostic factors (Figures 5A, B).
