Text: Multivariate analysis using a time-dependent Cox proportional hazards model showed that retransplantation (relative risk, 4. 6 [95 % CI, 1. 9 to 10. 7] ; P < 0. 001) ; total number of units of blood products administered during transplantation (relative risk, 1. 006 per unit [CI, 1. 003 to 1. 010] ; P < 0. 001) ; and presence of CMV disease (relative risk, 3. 9 [CI, 1. 8 to 8. 5] ; P < 0. 001), invasive fungal disease (relative risk, 3. 3 [CI, 1. 5 to 7. 1] ; P = 0. 0020), and bacteremia (relative risk, 2. 5 [CI, 1. 2 to 5. 2] ; P = 0. 0136) were independently associated with higher mortality rates.
