Recovery of hemoglobin levels after CAR-T therapy depending on the BT group. (A) Median hemoglobin levels over time depending on the BT group (non-CTX, intermediate CTX, and intensive CTX). Measured events per group and time point are provided in the table below. P values are shown to the right of the table and refer to comparisons of groups across time points and interactions between group and time points. Further statistical analyses using a linear mixed model are summarized in supplemental Table 8. Baseline, before LD. Day 0, day of CAR-T infusion. (B-C) Box plots showing the hemoglobin nadir values during the early (B) and late (C) post–CAR-T period depending on the BT group. The number of measurements per group and the P value of the group comparisons are given above. The framed numbers are the median values. The dashed lines indicate the threshold values for CTC grade 3 events. (D-E) The frequency of RBC transfusions during the early (D) and late (E) post–CAR-T period depending on the BT group. The P value of the group comparison and, if indicated, the results of a contingency analysis, including OR, 95% CI, and P value, are shown above. RBC, red blood cell.
