Survival estimates as a function of the number of bleeding sites. Median survival in patients with 1 bleeding site was 5.7 months, 2.8 months in 2 sites, and 2.3 months in 3+ sites. Simultaneous initiation of multiple bleeding had a median of 1.1 months. A significant difference was found between 1 and 2 bleeding sites (P = .0001) and between 2 and multiple sites (P= .0001). The difference between 2 and 3+ sites was not significant (P = .1). NBLD, patients who did not bleed within 100 days after transplantation.
