Figure 1. Correlation of serum NfL and DTI indices of the whole NAWM in the NfL(high) subgroup.

Figure 1

The serum level of NfL is moderately associated with fractional anisotropy (A), mean diffusivity (B), axial diffusivity (C), and radial diffusivity (D). The NfL(high) subgroup is comprised of patients with serum NfL above the median value of healthy controls (23.1 pg/mL). Shown are Spearman correlation coefficients (ρ) and p values. The black lines indicate the level and direction of the relationship. AD = axial diffusivity; DTI = diffusion tensor imaging; FA = fractional anisotropy; MD = mean diffusivity; NAWM = normal-appearing white matter; NfL = neurofilament light chain; RD = radial diffusivity.
