1 · What the graph read from 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.

2 · The registry

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

backgroundA complex interaction of host genetic and environmental factors may be relevant in the development of Helicobacter pylori (H. pylori)-related gastro-duodenal diseases. RANTES is a potent chemoattractant peptide for memory T lymphocytes and eosinophils, and has been shown to be enhanced in H. pylori-infected gastric mucosa. We aimed to clarify the effect of RANTES functional promoter polymorphism on the risk of gastro-duodenal diseases in a Japanese population.

methodsFour hundred and eighty-three subjects, comprising 106 gastric ulcer, 52 duodenal ulcer, and 325 non-ulcer subjects, were included in this study. Restriction fragment length polymorphism (RFLP) analysis was performed for polymorphisms at -28 C/G in the RANTES gene promoter region. Gastritis scores of antral gastric mucosa were assessed according to the updated Sydney system.

resultsThere were no significant differences in the RANTES promoter genotype distributions among non-ulcer subjects, ulcer patients, and gastric and duodenal ulcers. However, the degree of intestinal metaplasia was significantly lower among G carriers in H. pylori-infected subjects aged 60 years or older (C/C vs. G carriers; 1.28 +/- 1.02 vs. 0.83 +/- 0.89, P = 0.0357). In addition, we also found that the same genotype held a lower risk of more severe intestinal metaplasia in H. pylori-infected female subjects (C/C vs. G carriers; 0.91 +/- 1.03 vs. 0.41 +/- 0.73, P = 0.0443).

conclusionThe polymorphism of RANTES promoter is not associated with the susceptibility to peptic ulcer diseases, but the -28 G carrier is associated with a reduced risk of developing more severe intestinal metaplasia in H. pylori-positive subjects aged 60 years and older and in female subjects.
