OS and DOR after PSM. (A) OS after the infusion of CAR T cells according to histology (P = .0305). (B) DOR according to histology (P = .0610). Response rates are expressed as percentages with 95% CIs according to the exact Pearson-Clopper method and were compared via a χ² test. 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.
