Risk factors for late CMV disease. Forest plots presenting risk factors for first late CMV disease between day 100 and day 730 after HCT in the entire population (A) and in the PET cohort (B). Results from multivariable Cox proportional hazard models. Low-risk viremia is defined as <10 antigen-positive cells or viral load <1000 IU/mL; high-risk viremia as ≥10 antigen-positive cell or viral load ≥1000 IU/mL. cGVHD is time dependent. ∗Represents continuous variables. aGVHD, acute GVHD; ALC, absolute lymphocyte count; CNI, calcineurin inhibitor; HR, hazard ratio; MAC, myeloablative conditioning regimen; NMA/RIC, nonmyeloablative/reduced-intensity conditioning regimen; PBSC, peripheral stem cells.
