Dx, diagnosis; intermed., intermediate; IQR, interquartile range; NA, not available (ie, missing data); N/A, not applicable; num., number; PD, progressive disease; PR, partial response; PRN, as needed; SD, stable disease; ULN, upper limit of normal; vit., vitamins.
P values from Wilcoxon rank-sum test for continuous features and from Fisher exact test or Pearson chi-square test for categorical features.
Determined at DLBCL diagnosis for LC; missing for VC because the IPI component risk factors were determined at CART infusion not at diagnosis.
Determined at DLBCL diagnosis for LC, and at CART infusion for VC.
Data from the 27 patients in the LC who died before receiving CART cells will automatically be missing (ie, NA) for this feature.
