However, in terms of long-term survival, the 45-week survival rate was higher in the busulfan group (64.3%, 9/14 humanized mice) than in the irradiation group (20%, 4/20 humanized mice) and Kaplan-Meier survival analysis also showed a trend toward longer survival in busulfan group than radiation group ( figure 2B ; p =0.071).
