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
introductionGastroesophageal reflux is common in respiratory disease, but the interplay between gastrointestinal mechanisms that expose individuals to reflux and potentially aspiration, and lung mechanics and function remain incompletely understood. Our aim was to investigate this in patients with chronic obstructive pulmonary disease (COPD) and non-idiopathic pulmonary fibrosis (IPF) interstitial lung disease (non-IPF ILD), and compare with our published findings in IPF.
methodsFifty-seven patients with COPD (aged: 34-75 years) and 64 with non-IPF ILD (22-75 years) who underwent high-resolution impedance manometry and 24-hour pH impedance together with pulmonary function assessment were compared with 35 IPF patients (51-84 years).
resultsCOPD patients were less likely to exhibit ineffective esophageal motility (IEM) and/or absent contractility ( P = 0.009; P = 0.028), and tended to exhibit esophagogastric junction outflow obstruction (EGJOO) and/or hypercontractility ( P = 0.09, P = 0.14) than IPF and non-IPF ILD patients. Notably, integrated relaxation pressure correlated with esophageal length index (ELI) ( P = 0.048) and inspiratory LESP ( P = 0.003), with latter 2 correlating with each other ( P < 0.001). EGJOO patients tended to have fewer proximal reflux events and reduced pulmonary function, with the latter inversely correlating with ELI ( P < 0.05). Non-IPF ILD patients were less likely to exhibit EGJOO than COPD patients ( P = 0.27), and less likely to exhibit IEM ( P = 0.07) than IPF patients. However, those with IEM or EGJOO exhibited greater proportions of reflux events reaching the proximal esophagus than those with normal motility ( P < 0.03), which in contrast to IPF, seemed not to associate with worse pulmonary function. DISCUSSION: Associations between esophageal motility, and lung mechanics and function, and consequently reflux, are very disease-specific.
