Detailed organ toxicities after CD19 CAR T cells. (A) Number of patients with organ toxicities at each time point after CAR T-cell infusion (blue indicates total numbers of patients with toxicities at each time point; red indicates numbers of patients with new toxicity occurring during that individual time point). (B) The median duration of recovery of toxicities to grade ≤1 by organ systems (number on the right side of each boxplot indicates the median duration in days).
