Groups 2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code | Source |
|---|---|---|---|---|---|---|
| Group 1 | Chronic HF Without SDB | Patients with chronic heart failure (left ventricular ejection fraction ≤45% or New York Heart Association (NYHA) class III or IV or NYHA class II with ≥1 hospitalization within 12 months before inclusion) and no sleep disordered breathing (SDB, Apnoea-Hypopnoea Index AHI ≥15) | 2,566 | 3,686 | OG000 | ClinicalTrials.gov |
| Group 2 | Chronic HF With SDB | Patients with chronic heart failure (left ventricular ejection fraction ≤45% or New York Heart Association (NYHA) class III or IV or NYHA class II with ≥1 hospitalization within 12 months before inclusion) and sleep disordered breathing (SDB, Apnoea-Hypopnoea Index AHI ≥15) | 2,341 | 3,190 | OG001 | ClinicalTrials.gov |
