Data depicted as mean ± SD for normally distributed data and median (range) for nonparametric data.

BMI, body mass index; AHI, apnea hypopnea index.

^aP = 0.013 for controls vs. snorers and OSAS.

^bP < 0.0005 for controls vs. snorers and controls vs. OSAS; no difference between snorers and OSAS (P = 0.25).

^cP < 0.0005 for OSAS vs. controls and OSAS vs.snorers.
