TABLE 7.

Correlations between mean DTI change (FA, MD) and mean FEM (strain, strain rate) values in an MNI corpus callosum ROI (2685 voxels).

DTI
value
FEM value Correlation
(Spearman)
Correlation
(Pearson)
ΔFA Strain −0.11 (p < 0.001) −0.05 (p = 0.35)
ΔFA Strain rate 0.24 (p < 0.001) 0.23 (p = 0.01)
ΔMD Strain −0.34 (p < 0.001) −0.34 (p < 0.001)
ΔMD Strain rate −0.02 (p = 0.30) 0.0 (p = 0.87)

Because the justifications for the Spearman correlation may be weaker with this larger number of values, both Spearman and Pearson correlation results are included.
