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

objectivesHow alcohol consumption affects the integrity and the defense mechanisms of the mucosa in the upper gastrointestinal tract is largely unknown. We examined the effect of heavy alcohol use on gastric and duodenal Paneth-cell-derived and epithelial antimicrobial peptides (AMPs), cytokines, and the Wnt pathway, an important regulator of epithelial regeneration.

methodsIn 22 patients with heavy alcohol use and 17 control subjects, biopsies from gastric corpus, antrum, and duodenum were examined for messenger RNA (mRNA) of AMPs, cytokines, and Wnt pathway factors using real-time PCR. The expression of the α-defensin HD5 was analyzed immunohistochemically. The effect of alcohol exposure on Wnt signaling and AMP production was also studied in a gastric cell line using mRNA and reporter gene assays.

resultsHeavy alcohol use was associated with increased expression of Paneth cell HD5 and HD6 mRNA in the antrum, where these products are normally absent (HD5 mRNA in controls vs. PATIENTS: 2100±900 and 365 500±161 600, HD6 mRNA: 320±130 and 58 300±32 600 copies per 10 ng total RNA, means±s.e.m., P value: 0.022 and 0.011). Upregulated HD5 was independent of intestinal metaplasia that was observed in a minority of patients. No significant differences were found for β-defensins and cytokines (interleukins IL1β, IL6, IL8, IL10). In patients, Wnt pathway factors showed a trend toward higher levels. In vitro, ethanol exposure induced the production of HD5 and HD6 and activation of the Wnt pathway.

conclusionsAlcohol exposure can induce gastric Paneth cell AMP expression. This may be linked to Wnt pathway activation, which has an important role in the epithelial regenerative homeostasis.
