Frequency of FODMAP-rich products consumption and irritable bowel syndrome-like symptoms among amateur runners.
Article in Frontiers in nutrition, 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/objectives: Running may cause gastrointestinal symptoms resembling irritable bowel syndrome (IBS). One promising and widely studied tool to alleviate these symptoms is a diet restricting fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP). The aim of the study was to assess the relationship between the frequency of consumption of foods high in FODMAPs and the frequency of IBS-like symptoms among recreational runners. Materials and methods: The study included 153 recreational runners (81 women and 72 men) with a mean age of 37.8 ± 11 years. Most participants reported completing 3-4 training sessions per week (54.90%) and running 20-40 km per week (37.25%). Training intensity was not objectively assessed. Data were collected using the Computer-Assisted Web Interview method, a standardized questionnaire to assess the frequency of IBS-like symptoms, a proprietary questionnaire to assess behavioral and training factors, and food frequency questionnaire to assess the frequency of consumption of FODMAP-containing products. Results: Women scored significantly higher than men on the IBS symptom questionnaire (13.11 ± 4.82 vs. 10.71 ± 4.47; Conclusion: No significant association was observed between the frequency of consumption of FODMAP-containing products and IBS-like symptoms in this sample of amateur runners. The observed differences in symptom severity and the characteristics of training activity suggest that individual factors and gastrointestinal adaptation may play a role in the experience of symptoms. These results provide a starting point for further research that could more precisely determine the mechanisms influencing the occurrence of IBS symptoms in physically active individuals.
