Multivariable models for overall survival, nonrelapse mortality and relapse. (A) Stepwise multivariable Cox regression model for overall survival in patients age 40 years or older. Variables shown are those that significantly contributed to the model, with the exception of HCT-CI score, which was forced into the model. A complete list of variables offered for selection in the model is shown in supplemental Table 1. Multivariable models without HCT-CI are presented in supplemental Table 2. P values for overall significance: <.001 for recipient telomere length, <.001 for donor group, .16 for HCT-CI score. (B-C) Results of Fine-Gray models for nonrelapse mortality and relapse, respectively. The symbols represent the hazard ratios for nonrelapse mortality (in red) and relapse (in blue) and lines show 95% confidence intervals. Complete tables are shown in supplemental Table 3.
