Thirty-three participants completely responded to MAS, 11 were partial responders, and 27 were nonresponders. The proportion of female subjects was the highest in the responder group (39% (13/33) vs 27% (3/11) for partial-responders and 11% (3/27) for nonresponders. Partial-responders had a higher baseline AHI than responders and nonresponders (Sidak, p < .001 for both) and a higher BMI than responders (Sidak, p = .044). Responders had a smaller neck circumference than nonresponders (Sidak, p < .001). Finally, there was no difference in age between treatment outcome groups (p = .064). Continuous variables are presented as mean ± standard deviation. Statistical differences between MAS response categories were assessed using one-way ANOVA (
