Helicobacter pylori Gastritis as an Initial Presentation of Evolving Autoimmune Gastritis: A Report of Two Cases.
Article in Internal medicine (Tokyo, Japan), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 herein report two cases of evolving autoimmune gastritis (AIG) that were initially diagnosed as active Helicobacter pylori gastritis. Both presented with swollen gastric areas and erythema in the context of a current H. pylori infection. One patient progressed to overt AIG after H. pylori eradication therapy, while the other progressed after the spontaneous disappearance of H. pylori infection. At the time of the AIG diagnosis, the antral mucosa showed atrophic regression, while the corpus mucosa showed severe atrophy. Therefore, when swollen gastric areas with erythema are observed during active H. pylori gastritis, AIG should be considered.
