Prognostic impacts of different PM-MRD cut-off values. (A) Using the standard Log-Rank analysis, the optimal cut-off values of 2.34% and 10.0% were determined (X-axis denotes % PM-MRD). (B) Using the cut-off value of 2.34% allowed the discrimination of two patients groups with different EFS: 42.6% for PM-MRD^positive and 63.6% for PM-MRD^negative. (C) For the 10.0% cut-off value, EFS was 34.3% for PM-MRD^positive and 54.9% for PM-MRD^negative. (D) When the two were combined, three patient groups with different EFS rates were identified: 63.6%, 47.2%, and 34.3%.
