Survival, DFS, and relapse stratified by chimerism status. Kaplan-Meier estimates of OS, DFS, and the cumulative incidence of relapse are shown for (A-C) 65 patients with HLA-MMUDs, excluding 7 patients with primary graft failure, and (D-F) 180 patients with HLA-MUDs, excluding 13 patients with graft failure. Data are stratified by chimerism status with outcomes shown in red for patients achieving full donor chimerism by day +90 and in blue for patients with mixed chimerism. P values were calculated by using log-rank tests.
