For each participant, we calculated global properties of the binary SC network. S indicates the network connectivity density or sparsity. C_p, L_p, γ, λ, σ, and α denote the clustering coefficient, characteristic path length, normalized clustering coefficient, normalized characteristic path length, small-worldness and assortativity, respectively. For all participants considered, the SC networks exhibited a small-world (σ > 1) and assortative (α > 0) architecture, with the assortativity coefficient significantly (α_z−score > 1.64) higher than those in random networks. Notably, only 10 participants (ID: 2–11) that possessed DTI data were included in structural network analysis. n.a. denotes DTI data were not available.
