Effect of ANXA2 expression within the BM on EFS and OS. Shown are OS (A) and EFS (B; n = 154). Two groups of patients with low (ANXA2^low, black curve) and high (ANXA2^high, gray curve) ANXA2 expression. OS was significantly superior for low ANXA2 expression (P = .001); the same held true for EFS (P = .05).
