Analysis includes patients who are alive and free of subsequent HCT at day 100 landmark. Variables were chosen for inclusion by stepwise selection, with a P value of <.05 used as the criterion for inclusion. Infection history after CAR T-cell therapy was forced into the model. P values that are significant are indicated in bold.
CRS onset was treated as a time-dependent covariate.
