Fig. 3. Core association network (CAN) constructed from associations present in at least four participants.
Associations present in at least four networks were included in the CAN, which was clustered with the Walktrap method for community detection. Clusters are named after the most central taxa. Node color is mapped to the difference between median relative abundances for the Ruminococcaceae enterotype compared to other enterotypes. Therefore, the pink color indicates that a taxon was more abundant in the Ruminococcaceae enterotype, while a green color suggests that the taxon was less abundant in that enterotype. Node labels for higher taxonomic levels indicate that the taxon is an unclassified member of a taxonomic group. All edge weights were positive.
