Fig. 2: The interaction network of microbial genera in the HOS and LOS groups.

a The co-occurrence network of microbial genera in the HOS group. b The co-occurrence network of microbial genera in the LOS group. Nodes are sized and colored by their degree, while edges are thickened based on R value magnitude and colored red for positive or green for negative correlation. c The average degree of networks in the two groups. d The natural connectivity of networks in the two groups.
