Results of Multiple Linear Regressions for Determinants of REI During Sleep.
| r 2 | Coefficient | p | |
|---|---|---|---|
| ODI (4%) | .26 | ||
| AHI (events/h) | .44 | ||
| RRI dips index (dips/h) | 0.78 | 0.33 | .007 |
AHI = apnea-hypopnea index (event/h); ODI = oxygen desaturation index (4% desaturation/h); REI = Respiratory event index; RRI dips index = R-R interval dips index at 90% threshold (dips/h).
