Cumulative incidence of overall mortality in survivors at day 100 (n = 832) stratified by the maximum cytomegalovirus viral load before day 100 (A) and multivariable Cox proportional-hazard models assessing maximum cytomegalovirus viral load before day 100 as a risk factor for overall mortality (B). Covariates for overall mortality models were age, donor relation, transplantation year, underlying disease, disease risk, hemopoietic stem cell transplantation-specific comorbidity index score, neutropenia before day 100, and cytomegalovirus viremia after day 100 (time dependent). CI, confidence interval. (Reproduced from reference 107 with permission of Elsevier.)
