Prevalence of Helicobacter pylori Infection in Geriatric Adults: A Single-Center Cohort Study from Türkiye.
Article in The Turkish journal of gastroenterology : the official journal of Turkish Society of Gastroenterology, 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
BACKGROUND/
aimsHelicobacter pylori infection remains an important global health issue, particularly among older adults for whom related complications are more frequent. However, epidemiological data on the elderly populations in Türkiye are limited. This study aimed to determine the prevalence, associated factors, and endoscopic-histopathological correlations of H. pylori infection in a large geriatric cohort. MATERIALS AND
methodsThis single-center retrospective study included 2000 adults aged ≥65 years who underwent esophagogastro duodenoscopy between January 2023 and December 2024. Active infection was determined by stool antigen testing according to the Updated Sydney System. Demographic, clinical, endoscopic, and histopathological parameters were analyzed, and independent predic tors were identified using multivariate logistic regression.
resultsThe mean age of the participants was 77.5 ± 7.8 years, and 50.2% were male. The overall prevalence of H. pylori infections was 56.3%. Prior eradication therapy was independently protective (31.3% vs. 66.1%; P < .001). Infection rates did not differ significantly according to sex, smoking, alcohol use, or comorbidities. The highest positivity rates were observed for atrophic gastritis (60.8%), pan gastritis (58.0%), and antral gastritis (56.2%). The prevalence declined modestly in the oldest-old group (≥85 years), whereas atrophic and metaplastic changes increased with age.
conclusionHelicobacter pylori infection remains highly prevalent among elderly individuals in Türkiye, showing a gradual decline com pared with historical national data but a persistent association with premalignant mucosal changes. Early detection and individualized eradication strategies are essential to optimize geriatric gastrointestinal care. Cite this article as:Özden Y, Bulur O.
