ALDH^br impact on engraftment. Impact of ALDH^br measured on segments during CT on engraftment of the corresponding unit. Probability plots are shown for the units with an ALDH^br >0.5% of viable CD45⁺ or the units with an ALDH^br <0.5% of viable CD45⁺ in reaching an absolute neutrophil count of 500/μL. N = 78.
