Changes in the character of medical authorship. Aims To compare the impact of industry-linked and non-industry linked articles.
We compared articles on sertraline being coordinated by a medical writing agency with articles not coordinated in this way. We calculated numbers of Medline-listed articles per author, journal impact factors, literature profiles and citation rates of both sets of articles.
Non-agency-linked articles on sertraline had an average of 2.95 authors per article, a mean length of 3.4 pages, a mean Medline listing of 37 articles per author (95% CI 27-47) and a mean literature profile of 283 per article (95% CI 130-435). Agency-linked articles on sertraline had an average of 6.6 authors per article, a mean length of 10.7 pages, a mean Medline listing of 70 articles per author (95% CI 62-79) and a mean literature profile of 1839 per article (95% CI 1076-2602). The citation rate for agency articles was 20.2 (95% CI 13.4-27.0) and for non-agency articles it was 3.7 (95% CI 3.3-8.1).
The literature profiles and citation rates of industry-linked and non-industry-linked articles differ. The emerging style of authorship in industry-linked articles can deliver good-quality articles, but it raises concerns for the scientific base of therapeutics.
医学著者身份特征的变化。目的：比较与行业相关和与非行业相关文章的影响。
我们将由医学写作机构协调的有关舍曲林的文章与未以这种方式协调的文章进行了比较。我们计算了两组文章中每位作者在《医学索引》（Medline）上列出的文章数量、期刊影响因子、文献概况和引用率。
与非机构相关的舍曲林文章平均每篇有2.95位作者，平均长度为3.4页，每位作者在Medline上列出的文章平均为37篇（95%置信区间27 - 47），每篇文章的平均文献概况为283（95%置信区间130 - 435）。与机构相关的舍曲林文章平均每篇有6.6位作者，平均长度为10.7页，每位作者在Medline上列出的文章平均为70篇（95%置信区间62 - 79），每篇文章的平均文献概况为1839（95%置信区间1076 - 2602）。机构文章的引用率为20.2（95%置信区间13.4 - 27.0），非机构文章的引用率为3.7（95%置信区间3.3 - 8.1）。
与行业相关和与非行业相关文章的文献概况和引用率有所不同。与行业相关文章中新兴的著者风格能够产出高质量文章，但这引发了对治疗学科学基础的担忧。
