Correlation between cGFAP, cNfL, and sNfL levels in individual patients. The color of each box indicates the strength of association between the measurements in individual patients (Spearman’s r). The number in each box shows the P value for the Spearman rank-sum correlation. The “pre” time point for cGFAP and cNfL represents the prelymphodepletion sample, the “acute” time points represent the sample obtained on days 5 to 15 post CAR T-cell infusion. For sNfL, “pre” represents samples obtained on day 1 and “post” represents samples obtained from days 7 to 10.
