From: Co-occurrence of dental caries and periodontitis: multilevel modelling approach
Forest plot of the association between decayed- (DT) and filled teeth (FT) and bleeding on probing (BOP) stratified by age (≤ 44 years, 45–54 years, 55–64 years, ≥ 65 years). Odds ratios with their 95% confidence intervals (CI) for BOP from the two-level random intercept models adjusted for age, sex, sugar-containing diet, toothbrushing frequency, use of interdental care products, last dental visit, smoking, systemic diseases, use of medications, and xerostomia
