| Patient Characteristic | Total n = 60 |
|---|---|
| Age (yr) | 46.9 ± 11.8 |
| Male/female | 50/10 |
| BMI (kg/m2) | 27.9 ± 2.7 |
| Neck circumference (cm) | 40.8 ± 3.0 |
| Total AHI (events/h) | 15.9 (12.1, 26.0) |
| Supine AHI (events/h) | 36.4 (19.4, 65.3) |
| Nonsupine AHI (events/h) | 9.9 (3.9, 18.2) |
| TST in the supine position (%) | 39.3 (12.5, 51.5) |

Data are presented as mean ± SD or median (Q1, Q3). *MCP as a percentage of the maximal protrusion of the mandible during wakefulness. AHI = apnea-hypopnea index, BMI = body mass index, MCP = maximal comfortable protrusion, ODI = oxygen desaturation index, TST = total sleeping time.
