Data are presented as OR (95% CI). These multinomial logistic regression models are based on those variables that were included in preliminary analysis (table 4) plus a systematic assessment of the detailed obesity variables. Each of these models includes all variables forced in. AHI: apnoea–hypopnoea index; z: z-transformed; AWP: android/whole-body fat-mass proportion; GWP: gynoid/whole-body fat-mass proportion; VAT: visceral adipose tissue; SAT: subcutaneous adipose tissue.
