The role of natural products in the intestinal barrier: a bibliometric analysis from 2004 to 2025.
Synthesis in Frontiers in immunology, 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: There is an increasing number of studies on the protective effects of natural products on the intestinal barrier through multiple targets. However, the landscape of knowledge structure and emerging frontiers remains incompletely characterized. We conducted a bibliometric analysis and mapped the global landscape of natural products in intestinal barrier protection research. Methods: Using a predefined topic search strategy, we retrieved publications from the Web of Science Core Collection and PubMed from January 1, 2004 to November 6, 2025. We analyzed the complete records and citing literature using CiteSpace, VOSviewer, R (Biblioshiny), and SCImago Graphica to quantify the annual output and collaboration of countries/institutions/authors, and analyzed the influence of journals and publications through citation and co-citation analysis. We also detected the evolution of themes in the field through isomorphic keyword co-occurrence, clustering, and burst detection. Results: We included 1,679 records. 63 countries contributed to the development of this field, with China leading in productivity/paper output and influence (682 publications; 15,987 citations), followed by the United States and the United Kingdom. High-impact publications include Food & Function and Nutrients. Keyword analysis emphasizes that the gut microbiota, inflammation, and oxidative stress are the central pillars, and NF-κB signaling is the key mechanism hub. Polyphenols are the most studied category, and resveratrol is a representative cross-mechanism compound. Conclusion: The research scale in this field is expanding rapidly and is centered on the gut microbiota, linking immune inflammation and oxidative stress pathways with tight junction integrity and mucosal repair. Future work should strengthen cross-national cooperation and prioritize rigorous translational and clinical validation.
