Outcome after axi-cel stratified based on the category of BT. Kaplan-Meier curves starting from the time of axi-cel infusion, showing unadjusted PFS (A) and OS (B) comparing patients who received chemotherapy (chemo; n = 72), corticosteroids only (steroids; n = 37), radiation therapy alone (RT; n = 19), and targeted therapies (targeted; n = 15). Kaplan-Meier curves depicting PFS (C) and OS (D) after PS matching stratified based on any RT (n = 24) bridging vs non-RT bridging (n = 44). The ORR and CR rates in RT bridging vs non-RT bridging after PS matching (E).
