Altered oral microbiota in chronic hepatitis B patients with different tongue coatings

Figure 5 Associations of the tongue coating microbiotas with metabolites and clinical indices. Correlations were detected, and the indices with Spearman’s correlation coefficients > 0.3 were visualized in Cytoscape. Triangles represent clinical indicators, arrows represent metabolites and dots represent oral microbial families. If the correlations are negative, the connecting line is blue; if the correlation is positive, the connecting line is red. The line thickness represents the size of the correlation coefficient.
