Scatter plots of pre- (triangle) or post-AUC (circle) of MNC-binding ATG vs the day of neutrophil (top) or platelet (bottom) engraftment. The correlation between pre-AUC and neutrophil engraftment (P = .005) was significant, and the correlation between pre-AUC and platelet engraftment (P = .055) was near significant. There was no significant correlation between post-AUC and neutrophil or platelet engraftment.
