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 infection causes characteristic mucosal infiltration of inflammatory cells, resulting in the development of peptic ulcers and gastric cancer in approximately 10% of cases. Different clinical expressions of the infection may reflect different patterns of cytokine expression. Interleukin (IL)-1ss, tumor necrosis factor (TNF)-alpha, IL-17, and IL-18 have been reported to be involved in H. pylori-induced gastric mucosal inflammation, but the details and relation to different patterns of inflammation remain unclear. Moreover, the proinflammatory virulence factor outer inflammatory protein (OipA) was reported to be associated with gastric mucosal inflammatory cytokine levels. To clarify these findings, Mongolian gerbils were infected for up to 12 months with wild-type H. pylori 7.13 or with isogenic oipA mutants for 3 months, and mucosal cytokines (IL-1ss, IL-17, IL-18, and TNF-alpha) mRNA levels were then assessed using real-time RT-PCR. Antral mucosal IL-1beta and IL-18 mRNA levels peaked 1 month after infection, whereas the peak of TNF-alpha mRNA was at 6-12 months; IL-17 levels peaked at 12 months. The inflammatory cell infiltration and mRNA levels of all cytokines studied were significantly lower in oipA mutants than in wild-type-infected gerbils. Mucosal IL-1ss, IL-17, and TNF-alpha expression, but not that of IL-18, were significantly associated with the grade of inflammatory cell infiltration. The pattern of increased inflammatory cytokines differed relative to the phase of the infection and pattern of inflammation. OipA appears to play a role in IL-1ss, IL-17, and TNF-alpha expression and the resulting inflammation.
