Authorship is increasingly influential in career progression and academic promotion. This study aimed to examine authorship trends in surgical titles between 1998 and 2008, and to compare these trends with those in general medicine publications.
Clinical trials published in high-impact medical and surgical titles were identified. The number of authors associated with these studies and trends over time were analysed using PubReMiner. Trends were then compared between titles with and without author contribution forms (ACFs). Author numbers in top-cited articles were correlated with citation rates.
Some 6290 trials involving 54,120 different authorships were identified. A significant difference was found between authorship numbers associated with clinical trials in medicine versus those in surgery (P = 0.003). Introduction of ACFs did not influence the number of authors per trial (P = 0.670). The top 100 most highly cited articles accounted for 114,935 citations; author number correlated with subsequent citation rate (r = 0.26, P = 0.011).
Author numbers have increased in the past decade, in both medical and surgical journals. Although medical output is associated with significantly higher levels of authorship, the difference cannot be explained by complexity of research alone.
作者身份在职业发展和学术晋升中越来越有影响力。本研究旨在考察 1998 年至 2008 年间外科期刊的作者署名趋势，并将这些趋势与普通医学出版物进行比较。
确定发表在高影响力医学和外科期刊上的临床试验。使用 PubReMiner 分析这些研究与时间相关的作者数量和趋势。然后比较有和没有作者贡献表（ACFs）的标题之间的趋势。高引用文章的作者数量与引用率相关。
共确定了 6290 项涉及 54120 名不同作者的试验。医学与外科临床试验的作者人数存在显著差异（P = 0.003）。引入 ACFs 并未影响每个试验的作者人数（P = 0.670）。排名前 100 的高引用文章共获得 114935 次引用；作者人数与后续引用率相关（r = 0.26，P = 0.011）。
在过去十年中，医学和外科期刊的作者人数都有所增加。尽管医学成果与更高水平的作者身份相关，但这种差异不能仅用研究的复杂性来解释。
