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

Helicobacter pylori-associated gastric cancer is male predominant and animal studies suggest that sex hormones influence gastric carcinogenesis. We investigated the effects of 17β-estradiol (E2) or castration on H.pylori-induced gastritis in male INS-GAS/FVB/N (Tg(Ins1-GAS)1Sbr) mice. Comparisons were made to previously evaluated sham (n = 8) and H.pylori-infected (n = 8), intact male INS-GAS mice which had developed severe corpus gastritis accompanied by atrophy, hyperplasia, intestinal metaplasia and dysplasia of the epithelium within 16 weeks postinfection (all P < 0.01). Castration at 8 weeks of age had no sparing effect on lesions in uninfected (n = 5) or H.pylori-infected mice (n = 7) but all lesion subfeatures were attenuated by E2 in H.pylori-infected mice (n = 7) (P < 0.001). Notably, inflammation was not reduced but glandular atrophy, hyperplasia, intestinal metaplasia and dysplasia were also less severe in uninfected, E2-treated mice (n = 7) (P < 0.01). Attenuation of gastric lesions by E2 was associated with lower messenger RNA (mRNA) expression of interferon (IFN)-γ (P < 0.05) and interleukin (IL)-1β (P < 0.004), and higher IL-10 (P < 0.02) as well as decreased numbers of Foxp3(+) regulatory T cells when compared with infected intact males. Infected E2-treated mice also developed higher Th2-associated anti-H.pylori IgG1 responses (P < 0.05) and significantly lower Ki-67 indices of epithelial proliferation (P < 0.05). E2 elevated expression of mRNA for Foxp3 (P < 0.0001) and IL-10 (P < 0.01), and decreased IL-1β (P < 0.01) in uninfected, intact male mice compared with controls. Therefore, estrogen supplementation, but not castration, attenuated gastric lesions in H.pylori-infected male INS-GAS mice and to a lesser extent in uninfected mice, potentially by enhancing IL-10 function, which in turn decreased IFN-γ and IL-1β responses induced by H.pylori.
