FIGURE 3.

Associations of salivary S100A8, S100A12, MMP‐8, and TCC concentrations with periodontal parameters. Odds ratio for 10‐fold increase in concentration. Logistic regression adjusted for age, sex, smoking, diabetes, and the number of teeth. Error bars represent 95% confidence intervals for odds ratios. High ABL: ABL from moderate to severe; high PPD4: ≥ 17 sites with PPD 4 to 5 mm; high PPD6: ≥ 7 sites with PPD ≥ 6 mm; high BOP: BOP% ≥ 44. ABL, alveolar bone loss; BOP, bleeding on probing; MMP‐8, matrix metalloproteinase 8; OR, odds ratio; PPD, probing pocket depth; TCC, terminal complement complex
