Helicobacter pylori Infection Facilitates the Expression of Resistin-like Molecule Beta in Gastric Carcinoma and Precursor Lesions.

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 (H. pylori) was reported to be associated with gastric carcinogenesis. Resistin-like molecule beta (RELMβ), a recently described goblet cell-specific protein, was demonstrated to aberrantly express in gastric cancer and correlated with its clinicopathological features. This study aimed to examine the association between H. pylori and RELMβ expression in gastric carcinoma and precursor lesions. H. pylori infection and RELMβ expression were immunohistochemically evaluated in gastric biopsies from 230 patients. The biopsies consisted of normal gastric mucosa (n=20), mucosa with chronic gastritis (n=41), intestinal metaplasia (n=42), dysplasia (n=31), intestinal-type adenocarcinoma (n=56), and diffuse-type adenocarcinoma (n=40). RELMβ expression was measured in gastric biopsies after H. pylori eradication therapy in a subgroup of 32 patients. Cultured gastric cancer cell line SGC-7901 was infected with H. pylori strains, and RELMβ expression was detected by reverse transcription PCR, real-time PCR and Western blotting. Higher RELMβ immunoreactivity was observed in H. pylori-positive intestinal metaplasia (P=0.003), dysplasia (P=0.032), intestinal-type (P=0.037) and diffuse-type adenocarcinomas (P=0.001) than in H. pylori-negative specimens. Expression rates of RELMβ in dysplasia (P=0.005), intestinal-type adenocarcinoma (P<0.001), and diffuse-type adenocarcinoma (P=0.001) were significantly correlated with the grade of H. pylori density. In addition, H. pylori eradication reduced the RELMβ intensity in intestinal metaplasia (P=0.001). Infection of gastric cancer SGC-7901 cells with cag pathogenicity island (PAI)-positive H. pylori TN2, but not with its PAI totally deleted mutant (TN2-ΔPAI) for 4-8 h, resulted in enhanced protein and transcript levels of RELMβ (P<0.05). In summary, our study suggested that H. pylori infection facilitated the expression of RELMβ in gastric garcinoma and precursor lesions.
