Transient Blockade of Endothelin-1 Mitigates Amiodarone-Induced Pulmonary Fibrosis.
Article in Lung, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
introductionA number of studies indicate that endothelin-1 (ET-1) may act as an inflammatory cell "gatekeeper," by regulating the influx of neutrophils following pulmonary injury. To further examine the role of ET-1 in modulating lung inflammation, hamsters were treated with an endothelin receptor antagonist (ERA), HJP272, either 1 h prior to intratracheal instillation of amiodarone (AM) or 24 h afterwards.
methodsIn both cases, the extent of lung injury and repair was determined by (1) histopathological changes; (2) neutrophil content in bronchoalveolar lavage fluid (BALF); (3) lung collagen content; (4) tumor necrosis factor receptor 1 expression by BALF macrophages; (5) BALF levels of (a) transforming growth factor beta-1, (b) stromal cell-derived factor 1 (commonly referred to as CXCL12), and (c) platelet-derived growth factor BB; (6) alveolar septal cell apoptosis.
resultsFor each parameter, pretreatment with HJP272 resulted in a significant reduction compared to AM alone, whereas post-treatment was either ineffective or produced only a marginally significant change, suggesting that the course of lung inflammation and repair is programmed at a very early stage.
conclusionsThis finding may explain why ERAs are not an effective treatment for human pulmonary fibrosis. Nevertheless, they may be useful as an adjunct to therapeutic regimens involving drugs that have fibrogenic potential.
