  1. aMicrobial taxon (at genus level) with at least one significant (p < 0.001) and strong correlation (> 0.7 or < − 0.7)
  2. bNumber of connections/correlations obtained by the SpiecEasi algorithm
  3. cPercentage of SpiecEasi-positive correlation (> 0.7 with P < 0.001)
  4. dPercentage of SpiecEasi-negative correlation ( < − 0.7 with P < 0.001)
  5. eThe average number of connections per node in the network, the node connectivity
  6. fAverage network distance between all pairs of nodes or the average length of all edges in the network
  7. gThe longest distance between nodes in the network, measured in the number of edges
  8. hHow nodes are embedded in their neighborhood and the degree to which they tend to cluster together
  9. iThe degree of interconnectedness or the number of connections within the network
  10. jThe similarity or sameness of attributes among connected taxa
  11. kThe influence concentration using degree, closeness, and betweenness centrality metrics
