Table 2: Treatment outcomes with mandibular advancement appliance (MAA) therapy in relation to objective and subjective measures (n = 42). Measures are reported as mean (SD) or number (%).
| Variable | Pre-treatment | Post-treatment | p value |
| Apnoea-hypopnoea index (events/hour) | 21.0 (10.3) | 4.7 (3.0) | p < 0.001 |
| Therapeutic efficacy (%)* | 75.1 | ||
| Mean disease alleviation (%)** | 70.0 | ||
| Epworth sleepiness scale | 11.8 (5.1) | 7.2 (3.3) | p < 0.001 |
*Therapeutic efficiency (%) was calculated as follows: AHI baseline minus AHI with MAA in-situ, divided by the AHI baseline.
**Mean disease alleviation (%) was calculated as follows: adjusted MAA compliance × therapeutic efficacy ÷ 100.
