Adjusted HR and 95% CI from multivariable models evaluating CMV reactivation by day 100 as a risk factor for relapse at day 100 and 1 year after HCT. Covariates: 1, disease risk (low vs high, intermediate vs high); 2, cytogenetic risk (adverse vs intermediate and favorable vs intermediate); 3, patient race (other/unknown vs white); 4, cell source (bone marrow vs PBSC); 5, donor sex (female vs male); 6, conditioning regimen (reduced intensity vs myeloablative); 7, donor and recipient CMV serostatus (D+/R− vs D−/R−, D−/R+ vs D−/R−, or D+/R+ vs D−/R−); 8, acute GVHD (grade 3-4 vs 0-2).
