Logistic regression univariate analysis of predictors of obstructive sleep apnoea treatment success at the final visit (median time 373 days)

	OR (95% CI)	p-value
Age (baseline) years	1.04 (1.01–1.08)	0.01
Sex (female versus male)	2.62 (0.88–7.78)	0.08
BMI (baseline) kg·m−2	0.91 (0.83–0.99)	0.03
AHI (baseline) events·h−1	1.00 (0.98–1.03)	0.88
Therapy hours per week at post-titration visit	1.04 (0.99–1.67)	0.25
Therapy hours per week at final visit	1.02 (0.99–1.04)	0.22
Bilateral protrusion versus right protrusion	2.08 (0.96–4.51)	0.37
Other versus right protrusion	2.03 (0.50–8.21)	0.61

A multivariable model was fit with stepwise selection used to reduce the model to retain only significant parameters (age and body mass index (BMI)) and only age was retained. AHI: apnoea/hypopnoea index.
