Effect of CPAP vs. mandibular advancement device for excessive daytime sleepiness, fatigue, mood, sustained attention, and quality of life in patients with mild OSA.

Objective: This study's objective was to compare the best long-term treatment, mandibular advancement device (MAD) or continuous positive airway pressure (CPAP), for patients with mild obstructive sleep apnea (OSA) in improving excessive daytime sleepiness, fatigue, mood, sustained attention, and quality of life.

Methods: This study was a single-blind, parallel, randomized clinical trial with controls. The sample was composed of individuals between 18 and 65 years of age with a body mass index of < 35 kg/m and apnea/hypopnea index above five and less than 15.
