Table 4. Multiple Regression Analysis of Factors Influencing the Absolute Difference Between Respiratory Events Detected on DISE vs DISE-PG.
| Variable | β (95% CI) |
|---|---|
| Absolute difference in all obstructive events | |
| AHI | −0.02 (−0.63 to 0.60) |
| Hypopnea, % | −0.03 (−0.41 to 0.40) |
| BMI | 0.70 (−2.50 to 4.00) |
| MPH | 0.10 (−1.35 to 1.62) |
| NOS | −5.80 (−14.89 to 3.37) |
| Absolute difference in obstructive apnea events | |
| AHI | −0.19 (−1.27 to 0.70) |
| Hypopnea, % | −0.08 (−0.75 to 0.54) |
| BMI | 0.22 (−3.39 to 7.04) |
| MPH | 0.12 (−1.86 to 2.92) |
| NOS | −0.10 (−17.30 to 12) |
Abbreviations: AHI, apnea-hypopnea index; BMI, body mass index; DISE-PG, drug-induced sleep endoscopy; DISE-PG, drug-induced sleep endoscopy–polygraphy; MPH, distance from mandibular plane to hyoid; NOS, number of obstructive sites detected on DISE.
