Difference between nonsupine obstructive apnea-hypopnea index (AHI) and supine obstructive AHI (OAHI).

Predictors	Estimates	95% Confidence Interval	P value
Obesity class 1 vs 2/3	−.09	−2.40–2.22	.941
Age at procedure	−.22	−.52–.08	.160
Male	.41	−1.95–2.77	.734

Linear regression model for the nonsupine and supine obstructive apnea hypopnea index (OAHI) adjusted for age at procedure, sex, and obesity class. There is no significant difference in OAHI status when comparing age, sex, or class 1 to higher levels of obesity.
