To evaluate interventional radiology (IR) research over time based on the study type of published articles and the visibility of articles to non-radiology clinicians.
We performed a search of all PubMed-indexed literature from January 1, 1991, through November 11, 2020, for clinical IR articles classified by their study type, categorized as: 1) meta-analyses/systematic reviews/practice guidelines; 2) randomized controlled trials; 3) non-randomized controlled trials; and 4) longitudinal/observational studies. Clinical IR articles were defined as those that met keyword criteria constructed from Society of Interventional Radiology procedure guides. Data were also collected on medical specialty journal categories that published IR-related articles.
When we examined the first vs. the last decade of our study period, the number of IR articles published increased across all study types: randomized controlled trials (374 to 2620; 601% change), longitudinal/observational studies (2324 to 12,447; 436%), meta-analyses/systematic reviews/practice guidelines (1179 to 6135; 420%), non-randomized controlled trials (471 to 2161; 359%). The journal categories with the highest mean percentage increase of IR articles across all study types were obstetrics and gynecology (659%), peripheral vascular disease (342%), and emergency medicine (221%). We found a decrease of IR articles published in surgery (-6.0%), pediatrics (-14%), and pulmonary (-21%) journals.
The number of IR articles grew quickly and at a similar rate compared with all PubMed-indexed articles and increased as a proportion of articles published in non-imaging specialty journals. This indicates greater visibility of IR studies for all clinicians and is encouraging towards the advancement of IR techniques.
根据已发表文章的研究类型以及文章对非放射科临床医生的可见性，评估介入放射学（IR）随时间的研究情况。
我们检索了1991年1月1日至2020年11月11日所有被PubMed收录的文献，查找按研究类型分类的临床IR文章，分类如下：1）荟萃分析/系统评价/实践指南；2）随机对照试验；3）非随机对照试验；4）纵向/观察性研究。临床IR文章定义为符合根据介入放射学会程序指南构建的关键词标准的文章。还收集了发表IR相关文章的医学专业期刊类别数据。
当我们比较研究期间的第一个十年和最后一个十年时，所有研究类型发表的IR文章数量均有所增加：随机对照试验（从374篇增至2620篇；变化601%），纵向/观察性研究（从2324篇增至12447篇；436%），荟萃分析/系统评价/实践指南（从1179篇增至6135篇；420%），非随机对照试验（从471篇增至2161篇；359%）。在所有研究类型中，IR文章平均百分比增幅最高的期刊类别是妇产科（659%）、外周血管疾病（342%）和急诊医学（221%）。我们发现发表在外科（-6.0%）、儿科（-14%）和肺部（-21%）期刊上的IR文章有所减少。
IR文章数量增长迅速，与所有被PubMed收录的文章相比增速相似，并且在非影像专业期刊发表的文章中所占比例有所增加。这表明IR研究对所有临床医生的可见性更高，对IR技术的进步具有促进作用。
