Study Arms:
- Sleep apnea patients (Type: None): This group of patients will have been monitored over night with cardiorespiratory monitoring (CRM). CRM enables the physician to establish an Apnea-Hypopnea Index (AHI) which will be used for diagnosis. An AHI \> 15 is considered moderate-to-severe sleep apnea, and this is the focus group of patients in the current project.~These patients will be followed for 12 months during continuous positive airway pressure (CPAP) treatment. Adherence to the CPAP treatment will be closely monitored.

Based on this trial design, predict the completion outcome and termination type (if applicable).
