Table 2.
Home apnea screening results.
| Overall (n = 269) | Females (n = 214) | Males (n = 55) | |
|---|---|---|---|
| AHI (events/h) | 6.1 (2.7, 12.1) | 5.6 (2.7, 11.2) | 7.8 (3.4, 17.2) |
| Normal (< 5) | 43.5% | 46.3% | 32.7% |
| Mild (5 to < 15) | 37.2% | 37.4% | 36.4% |
| Moderate (15 to < 30) | 12.3% | 11.2% | 16.4% |
| Severe (30+) | 7.1% | 5.1% | 14.6% |
| Duration of evaluation (min) | 405.9 (328.6, 473.2) | 410.5 (327.6, 476.6) | 392.7 (329.1, 448.1) |
| Duration of recording (min) | 446.3 (376.6, 534.1) | 453.8 (381.9, 537.2) | 427.2 (366.9, 519.5) |
| Apnea index (events/h) | 1.0 (0.0, 4.0) | 1.0 (0.0, 3.0) | 2.0 (1.0, 8.0) |
| Hypopnea index (events/h) | 4.4 (1.7, 7.9) | 4.3 (1.6, 7.7) | 4.9 (2.0, 9.2) |
| Oxygen distress index (events/h) | 6.7 (2.3, 12.4) | 6.5 (2.2, 11.2) | 8.0 (2.8, 16.6) |
| Minutes saturation ≤ 90% | 15.0 (2.0, 109.0) | 14.0 (1.0, 101.0) | 28.0 (2.0, 122.0) |
Values are reported as percentage or median (25th, 75th percentile). Four cases were missing oxygen distress index and minutes saturation ≤ 90%. AHI = apnea-hypopnea index.
