Comparison of AHI(n/h) in patients with different severity in two places. Significant differences in patients with high-grade OSAS are found in the three tables below, representing differences in the likely severity of disease between the two patients.
| Plateau(n = 101) | Plain(n = 86) | T | P | |
|---|---|---|---|---|
| 5 ≤ AHI < 15 | 12.1(6.0-13.1) | 8.7(6.2–13.7) | 0.2 | 0.84 |
| 15 ≤ AHI < 30 | 23.7(19.2–27.5) | 22.9(17.9–26.9) | 0.27 | 0.79 |
| AHI ≥ 30 | 62(45.5–90.3) | 53.8(38.4–67.0) | 2.48 | 0.013* |
