FIG 3.

Networks in oral microbial communities under ECC and healthy conditions are shown, with each microbial species and cooccurrence relationship indicated by a node and an edge, respectively. A connection (line between dots) indicates a strong (Spearman’s ρ > 0.6) and significant (FDR < 0.05) correlation. The size of each node is proportional to the relative abundance. Lines between nodes indicate positive correlations (green) or negative correlations (red). The top five abundant genera are indicated in color.
