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

Background: The forced expiratory volume in 3 seconds (FEV Methods: Data were obtained from the National Health and Nutrition Examination Survey cycles 1988–1994 and 2007–2012. Reduced FEV Results: Overall, 25,159 participants were enrolled in the 308-month median follow-up analysis, of whom 8.8% (2225/25,159) had reduced FEV Conclusion: Participants with reduced FEV
