Neutrophil and platelet engraftment. (A) Neutrophil engraftment was defined as the first of 3 consecutive days with an absolute neutrophil count >500 cells/µL. Neutrophil engraftment occurred in all patients at a median of 15 days posttransplantation (range, 10-33 days). (B) Platelet engraftment was defined as the first of 7 consecutive days with a platelet count >20 000 cells/µL or >50 000 cells/µL without transfusion support. Platelet engraftment >20 000 cells/µL occurred in all evaluable patients at a median of 32 days posttransplantation (range, 15-56 days), and platelet engraftment >50 000 cells/µL occurred in all evaluable patients at a median of 37 days posttransplantation (range, 27-79 days).
