Note. n = absolute frequency and % = percentage. Samples: DP = dental patients with periodontitis, MHP = mental health patients with depressive symptomatology. Test: T = test statistic (B = binomial test, χ2 = Pearson’s chi-square test, t = Student’s t-test, ZU = Mann–Whitney U-test), p = probability value under the condition that the null hypothesis is true at a two-tailed test; a,b = each table superscript letter denotes a subset of categories whose row values do not differ significantly from each other at the 0.05 level of significance applying Bonferroni correction for multiple comparisons. * The category of “other occupation” was excluded in the calculation of the test.
