Effectiveness outcomes and associated risk factors. Kaplan-Meier estimates of (A) PFS and (B) OS for 416 patients overlaid with survival results extracted from ZUMA-1 study are shown. The x-axis shows days since administration of axi-cel. (C) Potential risk factors associated with PFSs using a multivariable Cox proportional hazard regression model are shown. Significant risk factors with P values ≤ 0.05 (adjusted for multiple hypothesis testing using the Bonferroni method) are highlighted with pink markers. LFTs, liver function tests; NE, not estimable; NR, not reached.
