Inclusion criteria
Inclusion criteria: Age 18–75 years.

Exclusion criteria
Exclusion criteria: Previous treatment with continuous positive airway pressure (CPAP) or any other positive airway pressure therapy. Predominant central sleep apnoea, defined as a central apnoea index accounting for >50% of the total apnoea–hypopnoea index (AHI), or the presence of Cheyne–Stokes respiration. Severe excessive daytime sleepiness posing an immediate safety risk, defined as an Epworth Sleepiness Scale (ESS) score >16 or occupational driving/machine operation associated with self-reported sleepiness-related near-miss events. Myocardial infarction, unstable angina, or stroke within the preceding 3 months. Decompensated heart failure (New York Heart Association [NYHA] class IV). Chronic respiratory failure or hypoventilation syndrome requiring bilevel positive airway pressure or other ventilatory support. Body mass index (BMI) >45 kg/m². Pregnancy or planned pregnancy during the study period. Current shift work with an irregular sleep–wake schedule.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome is the between-group difference in the change in SF-36 Vitality subscale score (range 0–100, higher indicating better vitality (Guermazi et al., 2012)) from baseline to 12 months, analysed in the intention-to-treat population. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary patient-reported outcomes are assessed using the ESS (Ahmed et al., 2014), the Fatigue Severity Scale (Al-Sobayel et al., 2016), the Hospital Anxiety and Depression Scale (Terkawi et al., 2017), and the EQ-5D-5L generic health-utility index (Group, 1990). Glycaemic status is summarised by the homeostasis model assessment of insulin resistance (HOMA-IR) (Matthews et al., 1985), and arterial stiffness by carotid, femoral pulse-wave velocity measured according to expert consensus methodology (Van Bortel et al., 2012). | — |
