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.
