PFS according to the indolent subgroup and CAR T-cell product after PSM. (A) PFS after infusion of CAR T cells according to the indolent subgroup (P = .0164). (B) PFS after the infusion of CAR T cells according to the CAR T-cell product: axi-cel (left graph) or tisa-cel (right graph). Time-to-event data were assessed via Kaplan-Meier curves, and the estimated rates at specific time points were computed with 95% CIs via the Greenwood formula. NA, not available.
