To determine the rate at which original studies that were presented orally at the 1995 Radiological Society of North America (RSNA) Scientific Assembly were published in Medline-indexed journals and to identify factors predictive of publication.
The 1995 RSNA Scientific Program was jointly reviewed by two readers. A total of 1,897 abstracts were included in the study. A Medline search of articles published between 1996 and 2000 was then conducted to identify articles written by the first, second, and/or last authors of all abstracts published in the 1995 RSNA Scientific Program. The year of publication, journal, country origin of the abstract, subspecialty, and nature of the research (ie, human, animal, or technical) were recorded. Publication rates were compared by using multiple logistic regression analysis.
Six hundred thirty-five abstracts were expanded into manuscripts that were subsequently published in Medline-indexed journals; thus, the publication rate was 33%. A study was published less than 3 years after the 1995 scientific assembly in 595 (94%) cases. Genitourinary radiology and chest radiology studies had the highest publication rates (46% and 48%, respectively; P <.01), whereas physics studies had the lowest (24%, P <.001). Technical studies (24%, P <.001) were less likely than human studies (36%, P <.001) to be published. The publication rate also differed substantially according to the country origin of the abstract. The articles were published in a total of 109 journals and chiefly in Radiology (211 cases, 33% of published studies).
One-third of original studies presented orally at the 1995 scientific assembly were subsequently published in Medline-indexed journals. More articles were published in Radiology than in any other identified journal.
确定在1995年北美放射学会（RSNA）科学大会上口头报告的原始研究在被Medline索引的期刊上发表的比例，并确定预测发表的因素。
两位读者共同审阅了1995年RSNA科学项目。该研究共纳入1897篇摘要。随后对1996年至2000年间发表的文章进行了Medline检索，以确定1995年RSNA科学项目中所有摘要的第一、第二和/或最后作者撰写的文章。记录发表年份、期刊、摘要的国家来源、亚专业以及研究性质（即人体、动物或技术研究）。使用多因素逻辑回归分析比较发表率。
635篇摘要被扩展为手稿，随后在被Medline索引的期刊上发表；因此，发表率为33%。在595例（94%）病例中，研究在1995年科学大会后不到3年就发表了。泌尿生殖系统放射学和胸部放射学研究的发表率最高（分别为46%和48%；P<.01），而物理学研究的发表率最低（24%，P<.001）。技术研究（24%，P<.001）比人体研究（36%，P<.001）发表的可能性小。发表率也因摘要的国家来源而有很大差异。这些文章共发表在109种期刊上，主要发表在《放射学》杂志上（211例，占发表研究的33%）。
1995年科学大会上口头报告的原始研究中有三分之一随后在被Medline索引的期刊上发表。发表在《放射学》杂志上的文章比其他任何已确定的期刊都多。
