The local network measures for group comparison were extracted from the SL matrix thresholded at 30% of connection density, where the C and λ of the SL network have the maximum values (Fig. 5). Group comparisons revealed reduced levels of node strength s at F4 (BD:NC = 2.96 ± 0.96:3.46 ± 1.32, p = 0.005; all p-values from permutation test), FC4 (BD:NC = 3.19 ± 1.10:3.75 ± 1.34, p = 0.005), Cz (BD:NC = 3.81 ± 1.15:4.36 ± 1.48, p = 0.008), C4 (BD:NC = 3.08 ± 0.95:3.56 ± 1.33, p = 0.009), and CP4 (BD:NC = 3.77 ± 1.21:4.39 ± 1.73, p = 0.01). With the sole exception of electrode site CP4, which showed a difference in the beta band, all other differences were observed only in the alpha band. In addition, local efficiency El differed in Cz (BD:NC = 0.27 ± 0.06:0.30 ± 0.08, p = 0.007), C4 (BD:NC = 0.26 ± 0.07:0.29 ± 0.08, p = 0.009), and CPz (BD:NC = 0.28 ± 0.07:0.31 ± 0.08, p = 0.008) in alpha band (Fig. 6). No differences were found for betweenness centrality b.
