| Risk in group 2 | 0.546 | 0.529 | 0.563 | wilson | ClinicalTrials.gov | |
| Risk difference, group 1 minus group 2 | -0.0141 | -0.0377 | 0.00956 | newcombe hybrid score | ClinicalTrials.gov | |
| Risk ratio, group 1 over group 2 | 0.974 | 0.932 | 1.02 | log | ClinicalTrials.gov | |
| Odds ratio, group 1 over group 2 | 0.945 | 0.859 | 1.04 | log | ClinicalTrials.gov | |
| Number needed to treat, for one fewer participant with the outcome on Chronic HF Without SDB than on Chronic HF With SDB | 71.1 | from the risk difference interval | the interval includes no difference | ClinicalTrials.gov |
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) | 1,961 | 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) | 1,742 | 3,190 | OG001 | ClinicalTrials.gov |
Outcome 5
| Field | Value | Source |
|---|---|---|
| Type | SECONDARY | ClinicalTrials.gov |
| Title | Ischemic Etiology | ClinicalTrials.gov |
| Description | Ischemic etiology describes a condition where a weakening or disease of the heart muscle is caused by reduced supply of blood (underlying cause might be the coronary artery). Secondary outcome ischemic etiology describes the cause of heart failure (HF) ischemic in HF patients without and with sleep-disordered breathing in percent of the respective study arm/group: e.g. x% of patients without SDB have HF with an ischemic etiology. | ClinicalTrials.gov |
| Time frame | 1-time: At baseline the ischemic etiology was determined in the medical institution or taken retrospectively from the medical records. | ClinicalTrials.gov |
| Population | ClinicalTrials.gov |
