FIGURE 7.

Relative abundance of the classical bacteria F. nucleatum vincentii, P. gingivalis, T. forsythia, and T. denticola associated with periodontitis. Bar plots showing the difference in relative abundance of the classical periodontitis pathogens between ecotype 1 and the three sub-ecotypes A, B, and C. Pairwise comparisons were tested using t-test or Wilcoxon test as appropriate with a Bonferroni correction. Mean with a different letter are significantly different (corrected p-value < 0.01).
