AML: acute myeloid leukemia; CI: confidence interval; OS: overall survival; WBC: white blood cell. Statistically significant results are reported in bold. a Log-rank tests. “Not available” category, not included in the calculation. b Only 5 (2.5%) patients had a favourable karyotype profile thus favorable and intermediate profiles were grouped together. c Distribution according to approximate quartiles.
