|---|---|---|

What is being measured
The primary outcome is the main question the study is designed to answer.
Therapeutic Efficacy
Determined by Apnea-Hypopnea Index (AHI) recorded on PAP therapy machines after 14 days of use. The Apnea-Hypopnea index (AHI) is the sum of the apneas and hypopneas divided by the hours of sleep. AHI values are typically categorized as 5-15/hr = mild; 15-30/hr = moderate; and >= 30/h = severe"
Measured: Baseline and 14±5 days
Epworth Sleepiness Scale
All relevant time points used in the calculation in the Time Frame (e.g., baseline and 14±5 days).
Note: change was calculated from two time points as the value at the later time point minus the value at the earlier time point (e.g., value at 14±5 days minus value at baseline).
Change between two time points is reported. Scale range: 0 (minimum score) to 24 (maximum score) (higher scores represent worse outcomes)
Measured: 14±5 days
