Healthy and CRC Bacterial Association Networks. Bacterial association networks presented in a circular layout. Edge color (green or red) represent positive or negative associations, respectively. Far left network (Shared Associations Network) shows the associations (edges) found in both the Healthy and CRC network. Node color within that network represents the phylum of the species. The two networks on the right are displaying the associations unique only to the Healthy or CRC network. Node color within these networks represent the module cluster this species was found within. Node size is a function of the node’s degree (total associations). For a list of species shown and not shown within networks see supplemental
