  1. aNodes represent bacterial taxa with co-occurrence correlation SparCC > or <  − 0.75
  2. bedges represent the number of connections/correlations
  3. cmodularity is the strength of division of a network into modules
  4. dmodules are sub-communities of bacteria that co-occur more frequently among each other than with other taxa
  5. enetwork diameter is the shortest path between the two most separated nodes
  6. faverage degree is the average number of links per node
  7. gweighted degree is the sum of the weight of all the edges connected to a node
  8. hclustering coefficient is the degree to which nodes in a network tend to form clusters
  9. itotal nodes and nodes with at least one edge are inside brackets
