Adjusted odds ratios (OR) and 95% confidence intervals (CI) of harmful alcohol use (AUDIT score ≥ 8) for higher CPI in total sample and each subgroup

	OR	95% CI
Total	1.158	0.969-1.383
Gender
Male	1.284	1.028-1.604
Female	0.803	0.565-1.139
Current smoker
No	1.291	1.058-1.575
Yes	1.003	0.717-1.403

The multivariate logistic regression model was adjusted for socio-demographic variables (age, gender, household income, educational level), oral health behaviors (daily frequency of toothbrushing, use of floss or interdental brush), general health behaviors (present smoking status), oral health status (active caries) and general health status (diabetes mellitus and obesity).

In the subgroup, each effect modifier was excluded from its multivariate model.
