Global research trends and foci of ablation therapies for liver tumours: a scientometric study.
Article in Journal of gastrointestinal oncology, 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: Ablation therapies have attracted sustained research interest in the management of liver tumours. This study aimed to systematically map global research trends, collaboration patterns, and the evolution of themes in liver tumour ablation using a scientometric approach. Methods: Publications related to liver tumour ablation were retrieved from the Web of Science Core Collection. Scientometric analyses, including network construction, co-authorship analysis, and keyword co-occurrence and burst detection, were conducted using VOSviewer and Citespace. Results: A total of 5,970 research articles between 1991 and 2022 were included. Publication output demonstrated continuous growth over the past three decades. The USA, China, Germany, Japan, and Italy were the most productive countries, with major contributions from institutions such as Sun Yat-sen University and Memorial Sloan Kettering Cancer Center. Authors and journal analyses revealed concentrated collaboration networks and diverse publication venues. Keyword analysis identified "hepatocellular carcinoma" and "radiofrequency ablation" as central research themes. In contrast, more recent research attention has shifted toward outcome-related and integrative topics, including overall survival, irreversible electroporation, and immunotherapy. Conclusions: This scientometric study provides a data-driven overview of the global research landscape in liver tumour ablation, highlighting growth in publications, collaborative structures, and evolving research themes. The findings delineate emerging areas of scholarly attention and offer a structured foundation for future bibliometric investigations into research priorities and thematic development in this field.
