1 · What the graph read from it

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.

2 · The registry

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

purposeChronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) are prevalent conditions with overlapping pathophysiological mechanisms. Their coexistence, termed overlap syndrome, is thought to amplify cardiometabolic risk. This study examined the 10-year risk of major adverse cardiovascular events (MACE) and all-cause mortality in individuals with COPD and OSA symptoms in a community-based cohort.

methodsBaseline data (1998-1999) from the Hordaland Health Study were linked to national registries on mortality and cardiovascular events. Of 7,456 eligible adults born 1925-1927 and 1950-1951, a random sample of 5,100 was invited, and 3,305 with valid spirometry were included. OSA symptoms were assessed by questionnaire, and chronic airway obstruction (CAO) was defined as post-bronchodilator FEV₁/FVC < 0.70. Cox regression estimated hazard ratios (HR) for MACE and all-cause mortality.

resultsCAO independently predicted both MACE (HR 1.48, 95% CI 1.12-1.97, p < 0.006) and all-cause mortality (HR 1.78, 95% CI 1.44-2.22, p < 0.001). Excessive daytime sleepiness (EDS) was associated with increased mortality (HR 1.37, 95% CI 1.01-1.85, p = 0.045). A significant interaction was found between CAO and habitual snoring, with participants displaying both having more than a twofold increased risk of mortality (HR 2.22, 95% CI 1.31-3.76, p = 0.003).

conclusionsCAO and EDS emerged as independent predictors of mortality, while the coexistence of CAO and snoring conferred synergistic risk. These findings highlight the need to recognize OSA symptoms in patients with obstructive lung disease, as they may identify a vulnerable subgroup at heightened risk. Future studies using objective sleep assessments are warranted to clarify mechanisms and guide preventive strategies.
