Chronic antiepileptic drug use and functional network efficiency: A functional magnetic resonance imaging study

Figure 1 Mean clustering coefficient (A and C) and global efficiency (B and D) for each risk category. Both clustering coefficient and global efficiency are normalized, i.e., the measures are divided by the clustering coefficient and global efficiency of random networks. A and B show the graph measures as a function of sparsity, while B and D show the results at a single sparsity level. Error bars show standard deviations, while the “*” indicate significant differences between the risk categories (P < 0.05, with age included as covariate).
