Two Decades of Medical Education Scholarship: Mapping Collaboration and Thematic Shifts Using Web of Science (2000-2019).

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
Introduction: The field of medical education (ME) has grown substantially over the past decades, yet questions remain about its scope and boundaries. This study examines how research topics and institutional collaborations have evolved in ME from 2000 to 2019. Methods: Adopting a post-positivist stance and using bibliometric network analyses, we examined metadata from 31,338 publications across 22 core ME journals indexed in the Web of Science. We analyzed trends in institutional collaboration and the development of research themes. Extracted metadata included authors' institutional affiliations and KeyWords Plus (n = 18,218). Bibliometric analyses were conducted using VOSviewer, a widely used tool for network mapping. We generated co-authorship networks to trace institutional collaboration and co-word networks to identify thematic clusters. Results: Co-authorship networks revealed increasing collaboration, with U.S. institutions remaining central and Canadian and Dutch institutions gaining prominence. Co-word analyses identified three stable clusters-teaching and learning, quantitative, and psychosocial-with teaching and learning dominant across all periods and the quantitative cluster expanding in recent years. Discussion: Findings show the consolidation of teaching and learning as the foundation of ME, alongside diversification through quantitative and psychosocial themes. Growing collaborations suggest the field's maturation, though geographic imbalances persist. Limitations include reliance on a restricted set of Web of Science journals, which overrepresent English-language and highly cited publications, and the use of KeyWords Plus as a proxy for themes. This study offers an evidence-based mapping of ME's evolution and provides a framework for future research on the interdisciplinary and global dynamics of the field.
