Global research trends in robotic coronary artery bypass grafting: a bibliometric analysis.
Article in Journal of thoracic disease, 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: Robotic coronary artery bypass grafting (CABG) has gained increasing attention as a minimally invasive approach to coronary revascularization. This study aimed to characterize the global research landscape, publication trends, and thematic evolution of robotic CABG through bibliometric analysis. Methods: Publications related to robotic CABG were retrieved from PubMed, Web of Science Core Collection, and Scopus databases, covering the period from January 1, 1997 to December 31, 2025. After data merging and deduplication, bibliometric analyses were performed using CiteSpace, VOSviewer, and the Bibliometrix R package. Annual publication trends, contributions by authors, institutions, countries, journal distribution, collaboration networks, co-citation relationships, and keyword co-occurrence patterns were systematically evaluated. Results: Research output on robotic CABG increased steadily over time, with more pronounced growth after 2015 and a peak in 2024. Original articles accounted for the largest proportion of publications. The United States was the leading contributor and the main hub of international collaboration, followed by Austria and Germany, while China showed increasing productivity in recent years. Key journals included Annals of Thoracic Surgery and Innovations. Thematic evolution demonstrated a change from early studies focused on technical feasibility toward later research emphasizing minimally invasive revascularization strategies and clinical outcomes including mortality, graft patency, survival, and quality of life. Conclusions: Robotic CABG research has expanded substantially over the past three decades, with its focus gradually changing from technical development to clinical outcome assessment. However, the evidence base remains limited by a predominance of observational studies from specialized centers and a lack of robust randomized comparative data. Future research should prioritize multicenter prospective studies assessing long-term efficacy, patient-reported outcomes, and cost-effectiveness to better define the role of robotic CABG in coronary revascularization.
