Bmi-1 expression was associated with ALL patient prognosis. a A total of 67 primary ALL patient samples were divided according to clinical outcomes. Patients who relapsed had significantly higher Bmi-1 expression levels than those who achieved CR after therapy. b The 3-year relapse-free survival (RFS) curves from a panel of 57 ALL patients. The cases were dichotomized based on the median expression of Bmi-1. Statistical differences between the curves were calculated by using the log-rank test, and the two-sided P value is indicated below the graph. **P < 0.01
