Figure 4. Associations between tract-specific microstructural readouts and clinical outcome above stenosis in patients with CSM.

Figure 4

(A,B) Overlay of statistical parametric maps (p < 0.01 uncorrected, shown for descriptive purposes, masked by the lateral corticospinal tract (CST) and posterior columns (PC), respectively) revealing associations between DTI indices and clinical outcome (left panel) between cervical level C2 and C3 (see Fig. 2A for reference). Colour bars indicate t-values. The right panels illustrate the corresponding regression models extracted from the peak-voxel within the significant cluster. Diffusivity parameters of the correlations are mean centered and adjusted for age. In particularly, (A) lower fractional anisotropy (FA) in left PC was associated with worse left ISNCSCI upper extremity light-touch score (UELT) and (B) lower FA in the left lateral CST was associated with lower Spinal Cord Independence Measure (SCIM).
