Baseline characteristics of patients randomized to MAD and CPAP.
| MAD (n = 43) | CPAP (n = 42) | |
|---|---|---|
| Age (years) | 50 ± 9.7 | 51 ± 9.8 |

| AHI (events/h) | 20.9 ± 4.4 | 21.0 ± 4.7 |
| Minimal oxygen saturation (%) | 83.6 ± 4.4 | 82.3 ± 4.2 |
| DM, n (%) | 4 (9) | 4 (10) |
| Type 1/type 2 | 1/3 | 0/4 |
| Smoking status, n (%) | ||
| Never-smoker | 18 (42) | 17 (40) |
| Ex-smoker | 10 (23) | 8 (19) |
| Current smoker | 15 (35) | 16 (38) |
| Medication use, n (%) | ||
| Antihypertensive medication | 10 (23) | 16 (38) |
| Cholesterol-lowering medication | 7 (16) | 5 (12) |
| Anticoagulation | 4 (9) | 4 (10) |
| Arrhythmias | 1 (2) | 1 (2) |
| Hypertension (140/90 and/or medication), n (%) | 14 (33) | 20 (48) |
Data are presented as mean ± SD or number, percentage. Differences between the MAD and CPAP group were not statistically significant. AHI = apnea-hypopnea index, CPAP = continuous positive airway pressure, DM = diabetes mellitus, MAD = mandibular appliance design, SD = standard deviation.
