(Left) Similarity between the modular structures of the functional networks for each participant pair, measured by normalized mutual information (NMI). The color-coded boxes placed along the NMI matrix diagonal represent the within-group modular similarity (CN = black, LLD = red, aMCI = blue, and aMCI-LLD = green). The between-group NMI values (mean ± SD) are listed in the lower triangular matrix. (Right) Histograms showing the mean and SD of the within-group NMI values for each group. Asterisks denote significant differences (p < 0.005) obtained by non-parametric post-hoc tests among the four participant groups. SD: standard deviation. Abbreviations: CN, cognitively normal; LLD, late-life depression; aMCI, amnestic mild cognitive impairment; aMCI-LLD, late-life depression comorbid with amnestic mild cognitive impairment.
