Data are presented as mean±se, unless otherwise stated. Significant differences (p<0.05) are presented in bold. Difference: apnoeic − normal. ^#: adjusted for race, age, height, fat pad volume and subspinale–nasion–supramentale (ANB) angle; ^¶: adjusted for race, age, height, fat pad volume, ANB angle and tongue volume; ⁺: significant after Bonferroni correction for multiple testing for all hypothesis tests.
