B, unstandardized coefficients; β, standardized coefficients; CI, confidence interval. The three craniofacial variables (lower face height, mandibular length, and maxilla-mandible relationship angle) were assessed for additional explanatory power for AHI changes, beyond weight change. The three craniofacial variables were considered as potential additional predictors (stepwise regression) to the unadjusted and adjusted models in Table 2. AHI and weight change are both expressed as either absolute change (∆) and percent change (%∆) in the respective models. The adjusted model for absolute AHI change (∆) included baseline BMI and waist circumference, as well as the original study participant, was recruited for (study). The adjusted model for percent AHI change (%∆) included sex, baseline BMI, and waist circumference, as well as study.
*p < 0.05.
– No craniofacial variables entered into the model (maxilla-mandible relationship angle was insufficiently predictive, p = 0.067).
