Differences in structural network properties between the LLD and non-LLD groups. (A) Rich-club organization and connection properties in each group. Red nodes represent rich-club members identified across all subjects, with node size indicating nodal connection strength. Colors distinguish between rich-club, feeder, and local connections. Bar charts illustrate group differences in these three connection types. (B) Schematic of clustering coefficient and group-wise differences in clustering coefficients. (C) Schematic of modularity and corresponding group differences. (D) Group differences in nodal efficiency across the structural network. Abbreviations: C, clustering coefficients; HIP.L, left hippocampus; INS.L, left insula; PCUN.L, left precuneus; AMYG.R, right amygdala. Statistical significance: *P < 0.05, **P < 0.01, ***P < 0.001
