Proportion of trajectories of change in inspiratory tongue movement pattern with mandibular advancement for each movement patterns observed with no advancement. All subjects where MAS altered inspiratory patterns for beneficial patterns had minimal movement at neutral position. In a larger proportion, beneficial and counterproductive patterns with the mandible in neutral position became minimal patterns with the mandible advanced. Individual changes in inspiratory dilatory patterns with mandibular advancement are reported in Table 3. Data labels: % (n subjects).
