1 · What the graph read from it

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.

2 · The registry

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: Type 2 diabetes mellitus (T2DM) is prevalent worldwide, with cognitive dysfunction emerging as a significant complication. Despite extensive research into its pathological mechanisms and clinical management, the knowledge structure, research priorities, and developmental trends within this field remain unsystematically integrated. Methods: To ensure comprehensive coverage and compatibility with bibliometric analysis tools, relevant publications on type 2 diabetes mellitus (T2DM) and cognitive dysfunction were primarily retrieved from the Web of Science Core Collection (WOSCC) database from its inception to November 5, 2025. Searches were also conducted in PubMed and Scopus to verify completeness, but the final dataset was derived mainly from WOSCC due to its optimal export format for CiteSpace (plain text with full records and cited references) and high overlap after deduplication. Employing bibliometric methods and tools such as CiteSpace (version 6.4 Advanced) and SCImago Graphica (version 1.0.39), we conducted visual analyses of publication trends, country/region collaboration, institutional distribution, author contributions, journal impact, co-cited references, and keywords. Results: A total of 1,752 publications were included. Annual publication volume exhibited a marked upward trend, accelerating particularly after 2018. China, the United States, and the United Kingdom were the primary contributing nations, with close inter-institutional collaboration. High-frequency keywords included 'type 2 diabetes mellitus', 'Alzheimer's disease', and 'cognitive impairment'. Research focus has shifted from early risk factors to microscopic levels, including neuroimaging, gut microbiota, and molecular mechanisms. Conclusion: Research on cognitive dysfunction in T2DM exhibits multidisciplinary characteristics, balancing fundamental research with clinical translation. Future efforts should enhance multidimensional integration of mechanism studies to advance early screening and personalised treatment strategies.
