FIGURE 3.

Discriminative performance of single CD3⁺ bone marrow cell chimerism values to predict subsequent relapse. The highest recorded chimerism value in CD3⁺ bone marrow cells from each hematopoietic stem cell transplantation (HSCT) for B‐acute lymphoblastic leukemia (ALL) was used to predict a subsequent relapse. Receiver operating characteristics (ROC)‐curves depict sensitivity and 1‐specificity of relapse prediction in (A) all patients (B) only pediatric patients and (C) only adult patients. Analysis includes chimerism values obtained from 30 days after transplantation to 30 days before clinical relapse or an equal length of time in the patients that did not have a relapse. TPR, true positive rate; FPR, false positive rate
