Bold values indicate statistically significant findings.

^*In some cases, there was no consensus on configuration, making the total amounts based on configuration findings differ from those for degree of obstruction.

DISE = drug induced sleep endoscopy, V = velum, CCC= complete concentric collapse, O = oropharyngeal lateral walls, T = tongue, E = epiglottis
