Pre-HSCT serum levels of Ang-2 lack association with percentage of bone marrow blasts, white blood cells, and peripheral blasts. (A) Pre-HSCT logAng-2 levels did not correlate with the percentage of bone marrow infiltration by leukemic blast (r = 0.085, P = .448), (B) white blood count (r = −0.035, P = .746), and (C) absolute peripheral leukemic blast count (r = 0.106, P = .322) using the Pearson correlation.
