TABLE 3.

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·m2 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.
