Figure 1.
The associations (OR) between periodontal parameters and the four bacteria investigated. ORs are calculated for the association between the periodontal parameters and highest levels of periodontal pathogen concentrations. The regression models were adjusted for the number of teeth and implants, age, gender, smoking, and diabetes. Error bars represent 95% confidence intervals. High ABL: ABL from moderate to severe compared to no to mild ABL; high PPD4: ≥17 sites with PPD 4–5 mm compared to < 17 sites; high PPD6: ≥7 sites with PPD ≥ 6 mm compared to < 7 sites; high BOP: BOP% ≥ 40 compared to < 40%, periodontitis: moderate to severe periodontitis compared to no to mild periodontitis. ABL, alveolar bone loss; PPD, pocket probing depth; BOP, bleeding on probing.
