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
backgroundH. pylori infection is less prevalent in childhood. This study validated whether the rates of H. pylori colonization depend on different acquisition ages, and correlate with the different gastric Lewis antigens or cytokine expressions after H. pylori acquisition.
methodsWe applied a young (7-day-old) C57BL/6 mice group (n = 50) and adult (6-week-old) C57BL/6 mice group (n = 50). In each group, 30 mice were challenged with H. pylori and 20 mice served as naïve control. The success of H. pylori colonization was assessed on the 2(nd )week and the 8(th )week, respectively. The intensity of the Lewis x, sialylated Lewis x(sialyl-Le(x)), and cytokine expressions, including TNF-α, IFN-γ, IL-6, IL-10, and IL-1β, were immunochemically stained and graded.
resultsOn the 2(nd )week after H. pylori challenge, the colonization rates of H. pylori were similar between the young mice group and the adult mice group (89% vs. 100%, P > 0.05). However, on the 8(th )week, the H. pylori colonization rate was significantly lower in the young mice group than in the adult mice group (53% vs. 95%, P = 0.003). On the 8(th )week, the young mice with a persistence of H. pylori colonization had higher sialyl-Le(x), higher IL-10, and lower IFN-γ than those of the mice that lost colonization during the 2(nd )to the 8(th )week (P < 0.05).
conclusionThe persistence of H. pylori colonization could be an acquisition-age determinant process. After H. pylori exposure at an early acquisition age, the host response with a higher sialyl-Le(x )and IL-10, but a lower IFN-γ correlates to the consequent persistence of H. pylori colonization.
