TOF, total occlusion force; NRT, natural/rehabilitated teeth number; NT, natural teeth number; Posterior, premolars and molars; Partial r, correlation coefficient
Crude¹: Mean ± Standard deviation; Adjusted.²: Mean ± Standard error
Superscript denotes the same subgroups by Bonferroni’s post-hoc multiple comparisons test
p value: obtained from T-test for crude values and ANCOVA for adjusted value after controlling for sex, age, alcohol drinking, smoking, education, periodontitis, metabolic syndrome and frailty
