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
The increasing antibiotic resistance of Helicobacter pylori (H. pylori) underscores the urgent need for alternative, nonantibiotic therapeutic strategies. This conceptual framework hypothesizes that Nitrosotalea devanaterra (N. devanaterra), an ammonia-oxidizing acidophile, could function as a biological competitor to H. pylori by reducing local ammonia availability, a critical factor for its survival and colonization in the gastric environment. To explore this hypothesis, a stepwise experimental framework is proposed. Initially, in vitro coculture models using gastric epithelial cells under microaerophilic conditions were employed to investigate potential interactions, metabolic competition, and impacts on H. pylori viability. Prospective in vivo validation could subsequently be performed using Mongolian gerbils, a model that closely mimics human gastric physiology, to assess the microbial load, histopathological changes, and host immune responses under controlled conditions. While direct empirical evidence for N. devanaterra survival and activity in the highly acidic gastric milieu is currently lacking, preliminary theoretical analysis suggests that ammonia competition could influence H. pylori persistence and pathogenesis. This hypothesis-driven approach emphasizes a microbiome-inspired strategy that does not rely on antibiotics, potentially reducing selective pressure for resistance. By introducing the concept of targeted nutrient competition as a therapeutic modality, this framework aims to stimulate further research into the feasibility of employing environmental acidophiles as modulators of pathogenicm bacteria in the stomach. The proposed strategy provides a foundation for future studies evaluating N. devanaterra or related ammonia-oxidizing microorganisms as innovative, nonantibiotic interventions against H. pylori infection.
