The probabilities of acute and chronic GVHD, non-relapse mortality, and overall survival. (A)The unadjusted cumulative incidence of grade 2 to 4 acute GVHD for recipients of MSD transplants with donors age 50 years or older and MUD transplants with donors age younger than 50 years. (B) The unadjusted cumulative incidence of chronic GVHD for recipients of MSD transplants with donors age 50 years or older and MUD transplants with donors age younger than 50 years. (C) The unadjusted cumulative incidences of NRM for recipients of MSD transplants with donors age 50 years or older and performance scores 90 or 100 (group A), MSD transplants with donors age 50 years or older and performance scores 80 or lower (group B), MUD transplants with donors age younger than 50 years and performance scores 90 or 100 (group C) and MUD transplants with donors age younger than 50 years and performance scores 80 or lower (group D). (D) Probabilities of OS adjusted for conditioning regimen, patient age, disease, and disease status for recipients of MSD transplants with donors age 50 years or older and performance scores 90 or 100 (group A), MSD transplants with donors age 50 years or older and performance scores 80 or lower (group B), MUD transplants with donors age younger than 50 years and performance scores 90 or 100 (group C) and MUD transplants with donors age younger than 50 years and performance scores of 80 or lower (group D).
