FIG. 3.
Group differences in characteristic path length (L) and clustering coefficient (C) as a function of network density. The changes in L (A) and C (B) of the AD and NL1 network over the network density range of 16–25%. Group differences in L (C) and C (D) between AD and NL1 network over a network density range of 16–25%. The gray lines indicate a 95% confidence interval defined by a permutation test with 1000 permutations. The + marker shows the difference between NL1 and AD networks (i.e., NL1metric – ADmetric); the + marker falling outside the confidence interval shows network densities at which between-group differences are significant. The positive values of + indicate NL1metric > ADmetric, whereas the negative values of + indicate NL1metric < ADmetric.
