Chronic mucosal inflammation of the gastric cardia in gastroesophageal reflux disease is not regulated by FOXP3-expressing T cells.

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
introductionChronic inflammation at the cardia occurs in gastroesophageal reflux disease (GERD), as well as in the presence of Helicobacter pylori. Regulatory T cells have been demonstrated for H. pylori-induced gastritis, whereas their role has not been studied in GERD.
methodsWe prospectively analyzed the expression of FOXP3, a marker of various regulatory T cells, as well as the mucosal transcript levels of TGF-beta1 and IL-10. RNA and protein levels have been determined in cardiac biopsies of 70 patients stratified according to GERD (n = 22), controls (n = 17), and H. pylori (n = 31).
resultsGERD presented with chronic inflammation and reduced FOXP3-mRNA in the cardiac mucosa (-84%), whereas H. pylori-positive patients revealed a 25.1-fold increase of FOXP3 gene expression. These results were verified by the regulatory cytokines IL-10 and TGF-beta1, and by the immunohistochemical detection of intramucosal FOXP3-expressing T cells.
conclusionChronic inflammation at the cardia associated with either GERD or H. pylori differs concerning the presence of FOXP3-expressing T cells. In contrast to H. pylori, FOXP3-expressing T cells are not associated with GERD-associated carditis.
