^aThe number of OTUs that were originally used for network construction using the random matrix theory (RMT)-based approach.

^bThe number of OTUs (i.e., nodes) in the network.

^cGD geodesic distance.

^dThe random networks were generated by rewiring all of the links of a pMEN with the identical numbers of nodes and links to the corresponding empirical pMEN.
