The correlation networks of subgingival species under different peridodontitis states. The co-occurrence correlation networks of subgingival samples under different peridodontitis states. Spearman correlations of relative abundances for all pairs of microbial species were calculated under different states of periodontitis respectively, with P-values adjusted by Benjamini-Hochberg correction, and selected those species pairs whose correlation coefficients were over 0.9 and adjusted P-values were less than 0.05 as the edges of networks. The size of point represents the average abundance of the species in samples
