Groups by clinical condition: GPS = General Population Sample (without diagnosis). Ging. = dental clinic sample with gingivitis, Period. = Dental Clinic Sample with a diagnosis of periodontitis. MR = Mean Range, D = Difference of ranks with a confidence interval of 95%, Z = test statistic, two-tailed p-value for Z-test *** p < 0.001, r = effect size calculated by transforming the Z-value to a linear correlation coefficient r = Z/N1/2.
