Pre-HSCT serum levels of Ang-2 and percentage of bone marrow blasts are predictors for disease-free survival after HSCT for high-risk myeloid malignancy. This figure illustrates the Kaplan-Meier curves of disease-free survival stratified to (A) Ang-2 (less than vs greater than median) and (B) bone marrow infiltration (< 50% vs > 50%) before allogeneic HSCT. Log-rank test confirmed statistical significance for Ang-2 (P = .011) and bone marrow infiltration (P < .001).
