  1. a) Because of significant interaction with age group (P = 0.005), logistic regression analysis was performed in three models stratified by age group.
  2. b) Patients treated for gingivitis and mild to moderate periodontal disease.
  3. c) Patients treated for severe periodontal disease.
  4. d) The proportion was compared by smoking status in the subpopulation receiving gingival/periodontal treatment in three age groups.
  5. e) Adjusted for gender.
