  1. Outcome: chewing problem (no versus yes)
  2. Odds ratio: obtained by multiple multivariable logistic regression adjusted for age, sex, education, periodontitis, smoking, alcohol drinking, metabolic syndrome and frailty
  3. TOF, total occlusion force; NTR, natural/rehabilitated teeth number; NT, natural teeth number; Posterior, premolars and molars
  4. Bold font indicates statistical significance
