Fig. 4.
RFS according to the MRD-based risk group classification as defined by MRD information at TP1 and TP2.
Patients in the low-risk group are characterized by MRD negativity at both time points, patients in the high-risk group are characterized by MRD levels 10−3 or greater at both time points, and the remaining patients form the intermediate-risk group. (A) 43 T-ALL patients. (B) 109 precursor B-ALL patients. For each MRD-based risk group, the number of patients and the relative size of each risk group are given. Tick marks indicate censored survival times.
