FAB indicates French-American-British classification; BM, bone marrow; FLT3 ITD, internal tandem duplication of the FLT3 gene; FLT3 TKD, a mutation in tyrosine kinase domain of the FLT3 gene; Mx, FAB not available; ND, not determined; —, not applicable; and SD, standard deviation.
P values were calculated using the 2-tailed chi-square test.
All patients with a specific abnormality were considered irrespective of the presence of additional abnormalities.
P values were calculated using 2-tailed t test.
