  1. TEAEs are reported unless otherwise specified
  2. AE, adverse event; axi-cel, axicabtagene ciloleucel; CI, confidence interval; CRS, cytokine release syndrome; ESS, effective sample size; LBCL, large B cell lymphoma; liso-cel, lisocabtagene maraleucel; MAIC, matching-adjusted indirect comparison; N, sample size; NA, not applicable; NE, neurological event; OR, odds ratio; SOC, system organ class; TEAE, treatment-emergent adverse event
  3. *MAICs not possible because all patients with grade ≥ 3 events would have been excluded during matching
  4. Represents TEAE assessed by investigators
