BACKGROUND
The publication rate of presented abstracts is an important parameter to assess the scientific quality of medical congresses. It has been investigated for many congresses in orthopaedics and traumatology, but until now, it has not been studied for the congress of the European Federation of National Associations of Orthopaedics and Traumatology (EFORT). The aims of this study were to determine: (1) the publication rate of the EFORT congress, (2) factors that favour publication of abstracts presented at the EFORT congress, (3) the consistency between the congress abstract and publication in relation to authorship.
HYPOTHESIS
There are factors that favour publication of abstracts presented at the EFORT congress and there is a high consistency between the congress abstract and publication in relation to authorship.
MATERIALS AND METHODS
All 1624 abstracts presented at the EFORT congress in 2011 were included in this study, to allow a 5-year period for publication after the congress. The characteristics of the abstracts presented were studied and the publication rate in peer-reviewed journals was determined using a Medline search.
RESULTS
The publication rate for studies presented at the 2011 EFORT congress was 42% (677/1624 abstracts), with a mean of 16 months (-56 to 60 months) between congress and publication. The mean impact factor of the publications was 1.8 (0-7.6). A significantly higher publication rate was found for: oral presentations (52%; 322/617) versus posters (35%; 355/1007) (p<0.01), experimental studies (53%; 110/208) versus clinical studies (40%; 507/1254) (p<0.01), and studies with higher levels of evidence of I or II (59%; 144/244) versus studies with lower levels of evidence of III or IV (36%; 362/1005) (p<0.01). A new author was added in 59% (403/677) of the publications.
DISCUSSION
Factors that favour publication of abstracts presented at the EFORT congress are oral presentation, experimental study, and a study with a higher level of evidence of I or II. It is common that a new author is added in the publication. Nevertheless, a high percentage of congress abstracts (58%; 947/1624) remains unpublished.
LEVEL OF EVIDENCE
IV, retrospective study.
背景
大会报告摘要的发表率是评估医学大会科学质量的一个重要参数。骨科和创伤学领域的许多大会都对此进行过研究，但截至目前，尚未对欧洲国家骨科与创伤学会联合会（EFORT）大会进行过研究。本研究的目的是确定：（1）EFORT大会的发表率；（2）有利于EFORT大会报告摘要发表的因素；（3）大会摘要与发表文章在作者署名方面的一致性。
假设
存在有利于EFORT大会报告摘要发表的因素，且大会摘要与发表文章在作者署名方面具有高度一致性。
材料与方法
本研究纳入了2011年EFORT大会上报告的所有1624篇摘要，以便在大会后有5年的发表期。研究了所报告摘要的特征，并通过检索Medline确定了在同行评审期刊上的发表率。
结果
2011年EFORT大会上报告的研究发表率为42%（677/1624篇摘要），大会与发表之间的平均间隔为16个月（-56至60个月）。发表文章的平均影响因子为1.8（0 - 7.6）。发现以下情况的发表率显著更高：口头报告（52%；322/617）高于海报展示（35%；355/1007）（p<0.01），实验性研究（53%；110/208）高于临床研究（40%；507/1254）（p<0.01），以及证据水平为I或II级的研究（59%；144/244）高于证据水平为III或IV级的研究（36%；362/1005）（p<0.01）。59%（403/677）的发表文章增加了新作者。
讨论
有利于EFORT大会报告摘要发表的因素包括口头报告、实验性研究以及证据水平为I或II级的研究。发表文章中增加新作者很常见。然而，仍有高比例的大会摘要（58%；947/1624）未发表。
证据水平
IV，回顾性研究。
