#N represents the total population; for individual variables, some data were not measured/reported, and the appropriate denominator is specified in these instances. Some percentages do not add up to 100 due to rounding.
*NCCN version was not specified in the original publication. As the patient enrollment commenced in 2012 in the CPX-351 study, we have classified the patients in the NBCR cohort using NCCN version 2.2011.
†FLT3 ITD versus TKD status was not specified in the original publication. The NBCR cohort included 8 patients with FLT3-ITD and 2 patients with FLT3-TKD.
