Impact of sport disciplines on gut microbiota in elite athletes: evidence from Taekwondo and diving athletes.
Article in Frontiers in microbiology, 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
Objective: Gut microbiota is closely associated with athletic performance, but differences between sport disciplines have rarely been reported. This study collected gut microbiota samples from athletes across different sport disciplines to further elucidate sport-specific effects on gut microbiota, thereby providing empirical evidence for the "exercise-gut microbiota" relationship within specialized athletic domains. Methods: Gut microbiota from 27 professional Taekwondo athletes and 11 diving athletes underwent high-throughput sequencing analysis. Results: (1) No significant difference existed in gut microbiota α-diversity between Taekwondo and diving athletes; (2) No significant differences were observed in gut microbiota structure (β-diversity) between Taekwondo athletes and diving athletes; (3) Intergroup differences existed in the gut microbiota of Taekwondo athletes vs. diving athletes; (4) Regarding KEGG pathways of gut microbiota between Taekwondo and diving athletes, 12 metabolic pathways showed significant differences. Specifically, lipid IVA biosynthesis and Kdo transfer to lipid IVA III pathways were lower in Taekwondo athletes than in diving athletes, whereas pathways including glycine biosynthesis of tetrapyrrole II, and inositol, chiro-inositol, and scyllo-inositol degradation were higher. Conclusion: Taekwondo athletes and diving athletes exhibit distinct differences in gut microbiota composition and multiple metabolic pathways, but show no significant difference in diversity.
