Figure 4From: Bacterial community composition of chronic periodontitis and novel oral sampling sites for detecting disease indicatorsHealth and disease associated phyla, by relative abundance. The top five most abundant phyla with significant differences between health and disease are shown. Significance was assessed with a Mann-Whitney test (P < 0.05). Disease abundances are shown in pale red, and health abundances in green. (A) All samples (SubG, SupG, and tongue). (B) SubG samples. (C) SupG samples. (D) Tongue samples. *0.01 < P < 0.05; **0.001 < P < 0.01; ***P < 0.001; ****P < 0.0001.Back to article page
