Flow scores and survival. (A) Cumulative incidence of relapse by flow score. Patients were assigned flow scores based on pretransplantation marrow analysis and outcome was analyzed using various cutoff values as described in the text. Shown are the cumulative incidences of relapse (figures at right margin) for the groups with mild (0-1), moderate (2-3), and severe (≥ 4) scores, respectively. (B) Survival. Kaplan-Meier estimates of survival by flow scores. Shown are survival estimates (figures at right margin) for patients with mild, moderate, and severe flow scores.
