For global network measures (clustering coefficients C, characteristic path length L, normalized clustering coefficients γ, normalized characteristic path length λ, small-worldness σ, and global efficiency Eg), permutation tests (10,000 times) were separately performed to determine the between-group differences on each network parameter for the varying thresholds of connection density (5, 10, … , 100%). This procedure followed the same analysis as the permutation tests for the mean SL values (see above, Mean SL). In addition, the role of each node in the SL network was examined by comparing each node-specific local network measures (strength s, betweenness centrality b, and local efficiency El) between BD patients and controls for all EEG nodes.
