Mortality impact of long-term home non-invasive ventilation in COPD patients with versus without obstructive sleep apnea.
Article in Annals of the American Thoracic Society, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
rationaleCoexisting chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) is known as overlap syndrome. This may represent a distinct clinical phenotype that shows different responses after being initiated on noninvasive ventilation (NIV) for hypercapnic chronic respiratory failure. However, current data remain scarce. OBJECTIVE(S): This study estimated the impact of overlap syndrome versus COPD without OSA on transitions between 3 states (without/recovery from severe exacerbation, severe exacerbation and death) in patients initiated on domiciliary NIV therapy.
methodsMultistate model data came from the French national health insurance reimbursement system database for individuals with COPD aged ≥40 years and ≥1 NIV reimbursement in 2015-2019. Outcomes in the overlap syndrome and COPD without OSA groups were compared using a Cox model and inverse probability of treatment weighting analysis, adjusted for patient characteristics.
resultsData from 54,545 patients were included (median age 70 years, 51.2% male). Probabilities of transitioning from severe exacerbation to death (10% vs. 22%) and without severe exacerbation to death (5% vs. 18%) were lower in the overlap syndrome versus COPD without OSA group. The rate of transition from severe exacerbation to without exacerbation/recovery was also higher in the overlap syndrome group. After NIV initiation, the mortality rate was 33% lower in people with overlap syndrome vs COPD without OSA.
conclusionsFor people with COPD started on domiciliary NIV, those with overlap syndrome might benefit from NIV to a greater extent than those without OSA. This highlights the need for OSA screening in people with COPD.
