Table 4.

The P values of Wilcoxon signed rank test for the homogeneity and discriminability between CI, T1wx2, and T1w of the LIBR data in subcortical regions. The value in the parenthesis after P value indicates the number of subjects who had decreased homogeneity or discriminability in the CI compared to T1wx2 or T1w.
