PDA score correlates with most known ICANS predictors and cytokines associated with ICANS. Correlation between the maximum PDA score and percentage of CAR T cells (n = 26; A), EASIX score at screening (n = 26; B), IFN-γ concentration (n = 12; C), IL-10 concentration (n = 12, D), GM-CSF concentration (n = 12; E), and IL-6 concentration (n = 12; F). Percentage of CAR T cells and cytokine measurements were performed at day 7 after infusion.
