Inhibition of Helicobacter pylori adhesion to Kato III cells by intact and low molecular weight acharan sulfate.
Article in Glycoconjugate journal, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
We investigated the inhibitory activity of glycosaminoglycans (GAGs) in terms of growth, adhesion, and VacA vacuolation of Helicobacter pylori. Intact acharan sulfate (AS, MW:114 kDa) potently inhibited H. pylori adhesion to Kato III cells with IC(50) value of 1.4 mg/mL, while other GAGs did not show any inhibitory activity except for heparin which is a well-known inhibitor of H. pylori adhesion. To investigate whether low molecular weight acharan sulfate (LMWAS) can inhibit H. pylori adhesion, we performed chemical depolymerization of AS by radical reactions to obtain LMWAS. Its physicochemical properties were characterized by high-performance size exclusion chromatography (HPSEC), agarose gel electrophoresis, disaccharide compositional analysis after digestion with heparinase II, and (1)H-NMR spectroscopy. The most potent molecular size of LMWAS was 3 kDa with IC(50) value of 32 μg/mL, which is 44-fold more potent than intact AS. These results suggest that AS as well as other GAGs can be chemically depolymerized by free radicals and LMWAS compared to intact AS can be applied as a pharmaceutical candidate in order to inhibit H. pylori adhesion to Kato III cells.
