Design outcomes

Primary

Measure	Time frame
1. Apnea-hypopnea index (AHI). 2. Oxygen Desaturation Index (ODI). 3. Sleep efficiency These outcomes will be assessed using simplified polysomnography (PSG) at baseline (preoperatively) and 1 year postoperatively. For patients without a preoperative PSG evaluation, exploratory assessments will be conducted at one, two, three and five years postoperatively, provided that informed consent is obtained at these time points.	—

Measure	Time frame
Arterial blood gas findings at baseline and, exploratorily, at 1 year postoperatively (only in patients with available data) Pulmonary function tests (%VC, FEV1, etc.) Epworth Sleepiness Scale for subjective sleepiness assessment Duration of apnea episodes measured by simplified PSG Quality of life assessment (e.g., SF-36, if available) Prognostic information (recurrence, rehospitalization, mortality)	—
