Citation analysis is a bibliometric method that uses citation rates to evaluate research performance. This type of analysis can identify the articles that have shaped the modern history of obstetrics and gynecology (OBGYN).
To identify and characterize top-cited OBGYN articles in the Institute for Scientific Information Web of Science's Science Citation Index Expanded and to compare top-cited OBGYN articles published in specialty OBGYN journals with those published in nonspecialty journals.
DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional bibliometric analysis of top-cited articles that were indexed in the Science Citation Index Expanded from 1980 to 2018. The Science Citation Index Expanded was queried using search terms from the American Board of Obstetrics and Gynecology's 2018 certifying examination topics list. The top 100 articles from all journals and the top 100 articles from OBGYN journals were evaluated for specific characteristics. Data were analyzed in March 2019.
The articles were characterized by citation number, publication year, topic, study design, and authorship. After excluding articles that featured on both lists, top-cited articles were compared.
The query identified 3 767 874 articles, of which 278 846 (7.4%) were published in OBGYN journals. The top-cited article was published by Rossouw and colleagues in JAMA (2002). Top-cited articles published in nonspecialty journals were more frequently cited than those in OBGYN journals (median [interquartile range], 1738 [1490-2077] citations vs 666 [580-843] citations, respectively; P < .001) and were more likely to be randomized trials (25.0% vs 2.2%, respectively; difference, 22.8%; 95% CI, 13.5%-32.2%; P < .001). Whereas articles from nonspecialty journals focused on broad topics like osteoporosis, articles from OBGYN journal focused on topics like preeclampsia and endometriosis.
This study found substantial differences between top-cited OBGYN articles published in nonspecialty vs OBGYN journals. These differences may reflect the different goals of the journals, which work together to ensure optimal dissemination of impactful articles.
引文分析是一种使用引文率来评估研究绩效的文献计量学方法。这种分析可以识别出那些塑造了妇产科现代历史的文章。
确定并描述科学引文索引扩展版中被引频次最高的妇产科文章，并比较发表在妇产科专业期刊和非专业期刊上的被引频次最高的妇产科文章。
设计、环境和参与者：这是一项对科学引文索引扩展版中 1980 年至 2018 年索引的高被引文章的横断面文献计量分析。使用美国妇产科委员会 2018 年认证考试主题列表中的检索词对科学引文索引扩展版进行了检索。评估了所有期刊的前 100 篇文章和妇产科期刊的前 100 篇文章的特定特征。数据于 2019 年 3 月进行分析。
文章的特征包括引用次数、出版年份、主题、研究设计和作者。在排除了同时出现在两个列表中的文章后，对高被引文章进行了比较。
该查询确定了 3767874 篇文章，其中 278846 篇（7.4%）发表在妇产科期刊上。被引频次最高的文章是 Rossouw 等人发表在《美国医学会杂志》（2002 年）上的一篇文章。发表在非专业期刊上的高被引文章比发表在妇产科期刊上的文章被引用的次数更多（中位数[四分位数间距]，分别为 1738 [1490-2077]次和 666 [580-843]次；P <.001），且更有可能是随机试验（分别为 25.0%和 2.2%；差异为 22.8%；95%置信区间为 13.5%-32.2%；P <.001）。非专业期刊的文章关注骨质疏松等广泛的主题，而妇产科期刊的文章则关注子痫前期和子宫内膜异位症等主题。
本研究发现，发表在非专业期刊和妇产科期刊上的高被引妇产科文章之间存在显著差异。这些差异可能反映了期刊目标的不同，它们共同努力确保有影响力的文章得到最佳传播。
