Relationship between peak copies of ssCAR-T-19 cell, bone marrow disease burden and CRS grade in r/r B-LL patients. (A) Comparison of ssCAR-T-19 cell expansion between patients with mCRS and sCRS. Mean values were calculated for each group. P-value was calculated using a Mann–Whitney U test. **means p-value <0.01. (B) Relationship between peak copies of ssCAR-T-19 cell, bone marrow disease burden, and CRS grade in r/r B-ALL patients. The bone marrow disease burden was divided into four groups. The y-axis represented the peak copies of the ssCAR-T-19 cells within 14 days after infusion. Mean values were calculated for each group and error bars indicate standard deviation. The different shapes of icons represented the grade of CRS. Red represented patients who achieved CR while blue represented patients who had no remission.
