.05 > P ≥ .01 are shown in bold and italic; P < 0.01 are shown in bold, italic, and underlined. Significant covariables retained for aGVHD: HLA-DRB3/4/5 matching, graft manipulation, and transplant center.
Significant covariables retained for relapse/progression (Rel/prog): European Society for Blood and Marrow Transplantation risk score, graft manipulation, and transplant center. CI, confidence interval; D, donor; Events, number of events in the risk category for the specified outcome; n, number of patients in the risk category for the specified outcome; R, recipient.
The number of patients/events for the regressions with expression is N = 579/191 and 558/212 for aGVHD ≥2 and Rel/prog, respectively.
Patients with nonmalignant disorder are excluded from analyses on relapse.
