Mapping the gut microbiota-diabetic peripheral neuropathy research landscape: a bibliometric analysis of emerging trends and translational frontiers.
Article in Frontiers in endocrinology, 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: Diabetic peripheral neuropathy (DPN) constitutes the most prevalent chronic complication of diabetes mellitus, affecting approximately 50% of patients throughout their disease course. Accumulating evidence indicates that gut microbiota (GM) dysbiosis plays a pivotal role in DPN pathogenesis via the gut-brain axis. However, a comprehensive bibliometric analysis delineating the intellectual landscape and evolutionary trajectory of this rapidly advancing research domain remains absent. Methods: Publications pertaining to gut microbiota and DPN were systematically retrieved from the Web of Science, PubMed, and Scopus databases (spanning 2010-2025). CiteSpace 6.4.R1 was employed to perform co-occurrence, clustering, timeline, burst detection, and co-citation analyzes, thereby visualizing the field's intellectual structure and developmental trends. Results: A total of 133 publications met the inclusion criteria, exhibiting exponential growth after 2018 with an average annual increase of 35.7%. Keyword analysis identified core research clusters centered on GM, neuropathic pain, the gut-brain axis, and therapeutic interventions such as fecal microbiota transplantation (FMT), traditional Chinese medicine, and causal inference methodologies like Mendelian randomization. Burst detection analysis revealed a temporal shift from foundational concepts (e.g., "oxidative stress", "inflammation") toward interventional strategies (e.g., "fecal microbiota transplantation", "traditional Chinese medicine") and causal inference approaches (e.g., "Mendelian randomization"). Co-citation analysis highlighted seminal contributions, including clinical trials demonstrating FMT efficacy and animal studies elucidating the role of microbial metabolites such as butyrate. Conclusion: This study presents the inaugural bibliometric analysis of the GM-DPN research field. The domain is transitioning from establishing associative links to elucidating causal mechanisms and evaluating targeted interventions. Keyword trend analysis underscores a convergence toward a multi-mechanistic gut-brain axis model. Future research priorities derived from the literature encompass clinical translation, multi-omics integration, and personalized therapeutic strategies.
