Multivariate stepwise logistic regression, with Oral Health Impact Profile (OHIP-14) dichotomised into less affected vs frequently affected, with Odds ratio (OR) and correspondent 95% CI

	OHIP-14 Total Score
	OR (95% CI)	p-value
Age	0.96 (0.93–0.99)	0.003**
SXI-5 Total	1.28 (1.14–1.43)	< 0.001***
PSS-10 Total	1.03 (1.00–1.05)	0.022*

Female	1	–
Male	1.44 (1.00–2.06)	0.048*
Mean CAL	1.25 (1.10–1.41)	< 0.001***

*The model was statistically significant, χ2(5) = 71.041, p < 0.001, explained 15.1% (Nagelkerke R²) of the variance and correctly classified 63.3% of cases
