Team science involving multidisciplinary and multi-institutional collaboration is increasingly recognized as a means of strengthening the quality of scientific research. The aim of this study was to assess associations between various forms of collaboration and the citation impact of published radiology research.
In 2010, 876 original research articles published in Academic Radiology, the American Journal of Roentgenology, JACR, and Radiology were identified with at least one radiology-affiliated author. All articles were manually reviewed to extract features related to all authors' disciplines and institutions. Citations to these articles through September 2016 were extracted from Thomson Reuters Web of Science.
Subsequent journal article citation counts were significantly higher (P < .05) for original research articles with at least seven versus six or fewer authors (26.2 ± 30.8 versus 20.3 ± 23.1, respectively), with authors from multiple countries versus from a single country (32.3 ± 39.2 versus 22.0 ± 25.0, respectively), with rather than without a nonuniversity collaborator (28.7 ± 38.6 versus 22.4 ± 24.9, respectively), and with rather than without a nonclinical collaborator (26.5 ± 33.1 versus 21.9 ± 24.4, respectively). On multivariate regression analysis, the strongest independent predictors of the number of citations were authors from multiple countries (β = 9.14, P = .002), a nonuniversity collaborator (β = 4.80, P = .082), and at least seven authors (β = 4.11, P = .038).
With respect to subsequent journal article citations, various forms of collaboration are associated with greater scholarly impact of published radiology research. To enhance the relevance of their research, radiology investigators are encouraged to pursue collaboration across traditional disciplinary, institutional, and geographic boundaries.
团队科学涉及多学科和多机构合作，越来越被认为是提高科学研究质量的一种手段。本研究旨在评估各种合作形式与发表的放射学研究的引文影响力之间的关联。
2010 年，从《学术放射学》、《美国放射学杂志》、JACR 和《放射学》中确定了至少有一位放射科附属作者的 876 篇原始研究文章。对所有文章进行了手动审查，以提取与所有作者学科和机构相关的特征。通过 Thomson Reuters Web of Science 提取了截至 2016 年 9 月对这些文章的引用。
随后的期刊文章引文计数对于至少有 7 位作者的原始研究文章明显更高（P <.05），而不是 6 位或更少的作者（分别为 26.2 ± 30.8 与 20.3 ± 23.1），有来自多个国家的作者与来自单个国家的作者（分别为 32.3 ± 39.2 与 22.0 ± 25.0），有而非没有非大学合作者（分别为 28.7 ± 38.6 与 22.4 ± 24.9），有而非没有非临床合作者（分别为 26.5 ± 33.1 与 21.9 ± 24.4）。在多变量回归分析中，引文数量的最强独立预测因子是来自多个国家的作者（β=9.14，P=.002）、非大学合作者（β=4.80，P=.082）和至少 7 位作者（β=4.11，P=.038）。
就随后的期刊文章引文而言，各种形式的合作与放射学研究发表后的学术影响力增加相关。为了提高其研究的相关性，鼓励放射科研究人员在传统的学科、机构和地理界限内进行合作。
