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.
