The gut-brain axis and anxiety: investigating associations with diet, vigorous activity, and prior adversity.
Article in Frontiers in psychology, 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
Introduction: The current study investigated associations between different stressors (e.g., poor diet, vigorous activity, and prior adversity), GI symptoms, and anxiety. Methods: We collected survey data from a sample of university students and community participants ( Results: Key findings included: (a) vigorous activity was a significant moderator of the relationship between stress and GI symptoms; (b) GI symptoms significantly mediated the relationships between stress and anxiety and prior adversity and anxiety; (c) stress and GI symptoms were significant serial mediators of the relationships between diet quality and anxiety and prior adversity and anxiety. Discussion: Our findings suggest that factors such as adversity, diet, and physical activity levels should be considered when examining gut-brain relations specific to stress, anxiety, and GI symptoms. Future research should investigate the directionality of these relationships more clearly through longitudinal and experimental study designs.
