Extracellular glutathione decreases the ability of Burkholderia cenocepacia to penetrate into epithelial cells and to induce an inflammatory response.
Article in PloS one, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundThe airway surface liquid (ASL) of Cystic Fibrosis (CF) patients contains a lower concentration of reduced glutathione (GSH) with respect to healthy people. It is not known whether this defect may favor lung colonization by opportunistic pathogens. PRINCIPAL
findingsWe have analyzed the effects of extracellular GSH on the ability of Burkholderia cenocepacia to penetrate and multiply in epithelial respiratory cells. Extracellular GSH proved to be able to drastically reduce the pathogen ability to adhere and invade airway epithelial cells. This effect is correlated to a GSH-dependent increase in the number of free thiols on the surface of epithelial cells, suggestive of a change in the oxidoreductive status of membrane proteins involved in B. cenocepacia recognition. Moreover, treatments with GSH led to a consistent reduction of the expression of IL-8, TNF-α and IL-1β in response to B. cenocepacia infection. CONCLUSIONS AND SIGNIFICANCE: Extracellular GSH modulates the interaction between B. cenocepacia and epithelial respiratory cells and inhibits the bacterial invasion into these cells. This suggests that therapies aimed at restoring normal levels of GSH in the ASL might be beneficial to control CF lung infections.
