Note. Samples: DPS = sample of dental patients with periodontitis, MHS = sample of mental health patients with depressive symptomatology, and GPS = general population sample. Variables: PR = predictor, PD = predicted variable, DS = depressive symptomatology (BDI-II total score), OHH = oral hygiene habits (OHHS total score), DPA = dental plaque accumulation (plaque index), and CAL = clinical attachment loss. Statistics: PE = point estimation through the maximum-likelihood method and 2-tailed probability value using Z-test: value ≤ 0.05, value ≤ 0.01, value ≤ 0.001, 95% CI = interval estimation with a confidence level of 95% through parametric (Monte Carlo) bootstrap method, LL = lower limit, and UL = upper limit.
