Mandibular advancement moved the tongue anteriorly to enlarge the oropharynx only for responders. Posterior tongue anterior movement due to mandibular advancement in partial- and nonresponders did not translate into upper airway enlargement. All data are presented as mean ± standard errors. All partial Pearson correlations between variables and mandibular advancement reported in this table between brackets were controlled for age, BMI and gender, and statistically accounted for the multiple measurements made within the same participants.
