Relapse incidence of patients with known MRD status and event-free at 12 months after allo-HCT (n = 38). The red curve shows the relapse incidence of patients who were MRD positive at the 12-month landmark post–allo-HCT (n = 10). The dark green curve shows the relapse incidence of patients who became MRD negative immediately after transplantation and remained so at the 12-month landmark (n = 11). The bright green curve shows the patients who became MRD negative only after immunosuppression tapering and remained so at the 12-month landmark (n = 17). HR, hazard ratio (reference red curve).
