Factors differentially associated with toxicities: TB, inflammatory markers, and key product attributes. Logistic regression analysis of the probability of grade ≥3 NE (left) or CRS (right) and baseline TB (A), the number of peak CAR T-cells normalized to TB (B), the number of CCR7⁺CD45RA⁺ CD8 T cells normalized to TB (C), baseline IL-6 (D), day 1 ferritin (E), day 1 CCL2 (F), baseline LDH (G), and IFN-γ (H).  P values were calculated using logistic regression.
