failed to achieve significancep = 0.094
While we found significantly lower sNfL absolute values in treatment naïve PwFD (median 9.7 pg/mL, IQR 7.7) compared to those receiving any disease-specific therapy (ERT or chaperone-therapy, 16.3 pg/mL, IQR 20.6, p = 0.015), this difference failed to achieve significance when analyzing sNfL Z-scores (0.75, SD 1.6 vs. 1.48, SD 1.4; p = 0.094, Table 4 ).
