Correlation between PSG parameters for in-laboratory study.
| PSG Parameter | n | Correlation (κ) | P |
|---|---|---|---|
| Arousals | 80 | 0.977 | < .001 |
| RDI | 81 | 0.995 | < .001 |
| Stage 1 (%) | 76 | 0.860 | < .001 |
| Stage 2 (%) | 76 | 0.845 | < .001 |
| SWS (%) | 76 | 0.851 | < .001 |
| REM (%) | 78 | 0.853 | < .001 |
Correlation between PSG parameters when comparing T1PSG and T2PSG for the in-laboratory study. PSG = polysomnography, RDI = respiratory disturbance index, REM = rapid eye movement, SWS = slow wave sleep, T1PSG = type 1 polysomnography, T2PSG = type 2 polysomnography.
