AHI: apnea/hypopnea index; NAS: nasal airway stent. In the snoring column, the symbol of + indicate the presence of snoring and - indicate absence of snoring.
AHI and snoring were recorded without NAS. Subject Nos. 22 and 23 refused to participate in this study at the beginning; hence, their AHI was referred from
results of a previous examination.
