Cytokine expression due to Helicobacter pylori in a tissue culture model.
Article in Molecular and cellular biochemistry, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Helicobacter pylori, in recent years, has been recognized as the major causative agent in chronic gastritis and peptic ulcer disease in humans. H. pylori is a ubiquitous organism, with at least half of the world's population infected. Of those individuals with peptic ulcer disease, it is estimated that 90% of cases are caused by H. pylori. Currently, the efficacy of therapies is starting to decline due to increasing resistance rates, especially towards clarithromycin. Due to this, new therapies are needed to combat this bacterium. It is hypothesized that cytokine release (especially interleukin-1beta, -6, -8, and TNF-alpha) due to H. pylori infection and the subsequent influx of inflammatory cells causes a massive release of reactive oxygen species (ROS) during the inflammatory reaction. The ROS then cause the pathologic changes seen in the infected tissues. In this study, human gastric adenocarcinoma cell line ATCC 1739 (a cell line not previously evaluated) was examined for its production of interleukin-1beta, -6, -8, and TNF-alpha when cocultured in a ratio of 10:1 H. pylori to adenocarcinoma cells, to determine its value as a model to demonstrate the inflammatory response. Results from this study indicated that ATCC 1739 cells only reliably produced IL-8 when cocultured with H. pylori and stimulated with TNF-alpha. The production of IL-1beta, IL-6, and TNF-alpha by the ATCC 1739 cells was no different in H. pylori-exposed cells than non-exposed cells. It was concluded that the ATCC 1739 cell line is not suitable to study the effects of coculture with H. pylori on cytokine production.
