a Modularity >0.4 suggests that the network has a modular structure.
b How nodes are embedded in their neighborhood, and the degree to which nodes tend to cluster together.
c The average number of steps along the shortest paths for all possible pairs of network nodes.
d Node connectivity showing how many connections (on average) each node has to the other nodes in the network.
eSmall-word coefficient >1 indicates “small-world” properties, that is, high interconnectivity and high efficiency.
The number in the brackets indicates the standard deviation of topological properties of the 1000 Erdös-Rényi random networks.
