在过去的六十年里,学术出版物的作者人数大幅增加,一种被称为作者身份膨胀的现象。本研究旨在分析比较作者的趋势和跨主要骨科多中心合作的影响,medical,和外科杂志。我们回顾了《新英格兰医学杂志》(NEJM)的元数据,外科年鉴(AS),和骨与关节外科杂志(JBJS)从1960年1月1日至2019年12月31日。每个出版物的作者数量,多中心研究的普遍性,并对其相关性进行了分析。使用热图和箱形图可视化数据,使用Jonckheere-Terpstra对趋势进行了统计测试,Mann-Kendall,和广义线性混合模型(GLMMs)。共分析了73062篇文章,1,190篇文章被确定为源自多中心研究。发现多中心试验的数量随着时间的推移显着增加(p<0.001),NEJM趋于稳定,但JBJS和AS继续上升。随着时间的推移,每份出版物的作者人数显着增加,所有日记帐(p<0.0001)。如确定系数(r2)所示,存在显着的统计相关性(p<0.0001),在所有三个期刊中,作者>10的出版物比例与多中心出版物比例之间的关联.学术出版中的作者人数膨胀可能归因于多中心合作的增加。与骨科期刊相比,医学和外科期刊的作者身份增加速度更为明显,反映不同专业的不同趋势。这些发现突出了学术出版中研究合作和作者实践的不断发展的性质。
Over the past six decades,
authorship numbers in academic publications have increased significantly, a phenomenon known as
authorship inflation. This study aims to analyze comparative
authorship trends and the influence of multicenter collaborations across major orthopedic, medical, and surgical journals. We reviewed metadata from The New England Journal of Medicine (NEJM), Annals of Surgery (AS), and The Journal of Bone and Joint Surgery (JBJS) from January 1, 1960, to December 31, 2019. The number of authors per publication, the prevalence of multicenter studies, and their correlation were analyzed. Data was visualized using heat maps and box plots, and trends were statistically tested using the Jonckheere-Terpstra, Mann-Kendall, and generalized linear mixed models (GLMMs). A total of 73,062 articles were analyzed, with 1,190 articles identified as originating from multicenter studies. The number of multicenter trials was found to have increased significantly over time (p < 0.001), plateauing in NEJM but continuing to rise in JBJS and AS. There was a significant increase in
authorship numbers per publication over time, across all journals (p < 0.0001). There was a significant statistical correlation (p < 0.0001) as indicated by the coefficient of determination (r2), for the association between the proportion of publications with >10 authors and the proportion of multicenter publications across all three journals.
Authorship inflation in academic publishing may be attributable to the rise in multicenter collaborations. The rate of increase in authorship was more pronounced in medical and surgical journals compared to orthopedic journals, reflecting differing trends across specialties. These findings highlight the evolving nature of research collaboration and authorship practices in academic publishing.
