Figure 2 Probability of leukemia-free survival after transplantation. The follow-up 1.5-60 months, 20 (60.6%) of thirty-three patients were still alive well. As shown in Figure 2, The probability of 3 year leukemia-free survival in AML patients was 68.0%, which was significantly higher than that ALL patients (45.0%, P=0.014).
