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

Objective: The aim of this study was to investigate the role of obstructive sleep apnea (OSA) on all-cause mortality in patients with COPD. Methods: Data for this cross-sectional study were obtained from the National Health and Nutrition Examination Survey (NHANES) data (year 2005-2008). Eligible subjects were ≥20 years who had no COPD or OSA (n=9,237), had only OSA (n=366), had only COPD (n=695), and had OSA/COPD overlap syndrome (n=90). Univariate and multivariate analyses were used to evaluate factors associated with overall mortality. Results: Multivariate analysis found that the COPD and OSA/COPD overlap syndrome groups had significantly higher chance of all-cause mortality than the group of subjects who did not have OSA or COPD (adjusted hazard ratio [HR] =1.5 for the COPD group and 2.4 for the overlap syndrome group) ( Conclusion: The present study found that COPD and OSA/COPD overlap syndrome were associated with higher all-cause mortality compared with patients without either disease and that OSA did not significantly increase mortality in patients with COPD.
