AML acute myeloid leukemia, sAML secondary AML, tAML therapy-associated AML, BMB bone marrow blasts, CR complete remission, HB hemoglobin, HCT hematopoietic cell transplantation, IQR interquartile range, n/N number, PBB peripheral blood blasts, PLT platelet count, WBC white blood cell count. Boldface indicates statistical significance (p < 0.05). *It has to be taken into account that mutated STAG2 is included as a marker of adverse risk in the novel ELN2022 risk stratification model and thus, partial collinearity may have diluted this specific result.
