Association of obstructive sleep apnoea with exercise capacity and mortality in a population-based study: results of SHIP-TREND.

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
Study objectives: Sleep and physical fitness are interrelated, with cardiovascular risk factors potentially influencing this relationship. Sleep disturbances and reduced exercise capacity are linked to higher mortality. This study examined associations between sleep characteristics, cardiopulmonary exercise testing (CPET) measures and all-cause mortality, and assessed whether reduced exercise capacity mediates the link between impaired sleep and mortality. Methods: We analysed 1001 participants from the population-based SHIP-TREND cohort (2008-2012) who underwent single-night polysomnography and symptom-limited CPET. Associations between sleep and CPET measures, as well as mortality, were assessed using multivariable linear and Cox regression models. Results: The mean age of participants was 54 (range 44-63) years; 47.1% were women. The apnoea-hypopnoea index (AHI) was 4.9 (95% CI 1.4-13.7) events·h Conclusions: In the SHIP-TREND-0 cohort, elevated AHI is associated with reduced
