Effect of chimerism on OS and EFS. Kaplan-Meier OS (A) and EFS (B) curve estimates among patients with NHL enrolled with CR or PR stratified by chimerism (complete or mixed chimerism, no graft failures occurred). Kaplan-Meier OS (C) and EFS (D) curve estimates among patients with de novo AML enrolled with disease control, CR1 or CR2 stratified by chimerism (complete, mixed, or primary graft failure). Corresponding 36-month OS or EFS noted.
