Enlargement of Gastric Hyperplastic Polyps Arising from Helicobacter heilmannii sensu stricto-infected Mucosa after the Successful Eradication of Helicobacter pylori and the Long-Term Use of a Proton Pump Inhibitor.
Article in Internal medicine (Tokyo, Japan), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Helicobacter pylori eradication is effective for the regression of gastric hyperplastic polyps (GHPs). We report a case which demonstrated an enlargement of GHPs after H. pylori eradication. The patient, who received long-term proton-pump inhibitor (PPI) therapy, lived with a dog, a natural host of Helicobacter heilmanii sensu stricto. Gastric colonization with Helicobacter heilmannii s.s. was observed after H. pylori eradication, thus suggesting the involvement of non-H. pylori Helicobacter species (NHPHs) infection for the enlargement of GHPs, in addition to the proliferative effects of PPI use on the gastric epithelium. Screening for NHPHs may be necessary in dog lovers to avoid paradoxical responses to H. pylori eradication.
