Collaboration is one of the hallmarks of academic research. This study analyzes collaboration patterns in U.S. transplant research, examining publication trends, productive institutions, co-authorship networks, and citation patterns in high-impact transplant journals.
4,265 articles published between 2012 and 2021 were analyzed using scientometric tools, logistic regression, VantagePoint software, and Gephi software for network visualization.
16,003 authors from 1,011 institutions and 59 countries were identified, with Harvard, Johns Hopkins, and University of Pennsylvania contributing the most papers. Odds of international collaboration significantly increased over time (OR 1.03; p = 0.040), while odds of citation in single-institution collaborations decreased (OR 0.99; p = 0.016). Five major scientific communities and central institutions (Harvard University and University of Pittsburgh) connecting them were identified, revealing interconnected research clusters.
Collaboration enhances knowledge exchange and research productivity, with an increasing trend of institutional and international collaboration in U.S. transplant research. Understanding this community is essential for promoting research impact and forming strategic partnerships.
合作是学术研究的标志之一。本研究分析了美国移植研究中的合作模式，考察了高影响力移植期刊上的发表趋势、高产机构、共同作者网络和引用模式。
使用科学计量工具、逻辑回归、VantagePoint软件和用于网络可视化的Gephi软件，对2012年至2021年间发表的4265篇文章进行了分析。
确定了来自1011个机构和59个国家的16003名作者，其中哈佛大学、约翰·霍普金斯大学和宾夕法尼亚大学贡献的论文最多。国际合作的几率随时间显著增加（OR 1.03；p = 0.040），而单机构合作中的被引用几率则下降（OR 0.99；p = 0.016）。确定了五个主要科学社区以及连接它们的核心机构（哈佛大学和匹兹堡大学），揭示了相互关联的研究集群。
合作促进了知识交流和研究生产力，在美国移植研究中，机构和国际合作呈增加趋势。了解这个群体对于提高研究影响力和形成战略伙伴关系至关重要。
