Complex microbial interaction networks based on 177,147 simulations. Each node represents a genus. Node color represents degree, node size represents betweenness centrality, and text size represents closeness centrality. The color of the edge represents the strength of the interaction between two nodes. a Microbial interaction network of Sham group; n = 3. b Microbial interaction network of SNI group; n = 3
