Age distribution of investigated patients. The age distribution of all analyzed patients (n=2345) is summarized. Upper part: diagram displaying ALL and AML patients. Age at diagnosis was divided into infants (0–1 year), pediatric (1–18 years) and adult patients (>18 years). The number of ALL, AML and other patients is listed below. We also added the information about therapy-induced leukemia (TIL) patients, the number of complex MLL rearrangements (CL) and specified the ‘non-ALL’ and ‘non-AML’ patients (MLL, MDS, lymphoma and other) in more detail for each age group. The precise number of all patient cases is summarized on the right.
