Table 1 Network topological characteristics. Global statistics were calculated based on co-occurrence network comprising all significant microbe-microbe correlations at α < 0.001 while top 50 statistics were calculated based on simplified network that including only the top 50 nodes with the most connections to other microbes

  1. aPositive ratio represents the ratio of positive microbe-microbe correlations out of all interactions within the network
  2. bEdge density was calculated as the ratio of detected edge numbers to the theoretical maximum edge numbers, indicating the connectiveness between nodes
  3. cAve. degree was defined as the mean connection degree across all nodes within a network
  4. dAve. Betweenness was defined by the average number of shortest paths going through all vertices within a network
