Basic sleep study data
| All patients | |
|---|---|
| All values are expressed as median (IQR) except †mean (SD). | |
| *Significant difference from RDI-total study assessed by Mann-Whitney tests. | |
| RDI-total study = respiratory disturbance index per hour of study; RDI-lights out = respiratory disturbance index during the night only; RDI-worst hour = respiratory disturbance index during the hour when UAO was at its most severe; DI = desaturation index per hour of study. | |
| RDI-total study (events/h) | 14.5 (7–25.3) |
| RDI-lights out (events/h) | 29.7 (13.5–40)* |
| RDI-worst hour (events/h) | 42.5 (21.3–55.8)* |
| 4% DI (desaturations per hour) | 33 (10–70) |
| Time saturation <90% (min) | 13.5 (4–55) |
| Baseline oxygen saturation (%) | 94.3 (2.2)† |
| Snores per hour | 33 (8.2–54) |
