CI, confidence interval.

Lee et al¹² criteria were used to determine CRS toxicity grade, and National Cancer Institute Common Terminology Criteria for Adverse Events (version 4.03)¹⁷ were used to determine NE toxicity grade.

†

Percentages based on patients who experienced a CRS and/or NE episode.

‡

95% CIs estimated from probabilistic sensitivity analysis applied to base case median costs to impute 95% CIs for base case.
