Estimated coefficients and values (in brackets) for the 4 seemingly unrelated regressions. Only variables abutting almost one significant correlation are reported. FMPS: full-mouth plaque score; FMBS: full-mouth bleeding score; PSR: periodontal screening and recording; PRA: periodontal risk assessment; NoC: number of cigarettes (per day); : number of hopeless teeth extracted during cause-related therapy. b: baseline; Δ: Δ-check (maximum gap between check-I, check-II, and check-III).
