Endoscopic Lung Volume Reduction Results in Improvement of Diaphragm Mobility as Measured by Sonography.
Article in International journal of chronic obstructive pulmonary disease, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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: Hyperinflation in patients with pulmonary emphysema is an important cause of reduced diaphragm mobility. We investigated whether endoscopic lung volume reduction (ELVR) could improve diaphragm mobility. Methods: Diaphragm mobility data obtained by sonography from 44 patients were compared before and 3-6 months after ELVR therapy with a Spiration™ valve system. These patients were asked whether they wanted this procedure again after they had learned of their treatment outcome; this was a subjective indicator of outcome. Lung function parameters and blood gases were also measured. Results: After ELVR, 30 patients (82%) developed atelectasis of ≥50% of the targeted lung lobe. These patients had a diaphragm mobility increase of 28.97 ± 15.93 mm, while the remaining patients experienced an improvement in diaphragm mobility of 16.07 ± 21.17 mm; this difference was significant (p = 0.030). All 30 patients with atelectasis and additional 6 patients without radiologically demonstrated atelectasis perceived an improved outcome after ELVR. Their diaphragm mobility increased by 28.89 ± 17.26 mm. Conversely, the patients with no perceived improvement in outcome had a diaphragm mobility increase of 6.75 ± 12.76 mm; this difference was significant (p = 0.001). Conclusion: ELVR can improve diaphragm mobility, and this improvement is correlated with a perceived positive outcome in patients.
