Abstract presentations of scientific information at meetings are important for broadcasting new information. Publication of these studies should be the final goal, but minimal data exist documenting publication rates, especially for paediatric sub-speciality meetings. The goal of this study was to document the manuscript publication rate for paediatric cardiac echocardiography abstracts and to determine whether there were differences between abstracts that were published versus not published.
Paediatric cardiac echocardiography abstracts presented from 2007 to 2011 at the American Society of Echocardiography Meetings were reviewed. Characteristics of the abstracts were noted. A Medline/Pubmed search was performed using keywords, first author, and senior author criteria to determine publication. Fisher's exact tests or χ2 tests were used for analysis.
A total of 194 abstracts were reviewed. In all, 27 abstracts were oral presentations and 167 were poster presentations. A total of 124 abstracts were prospective studies and 70 were retrospective studies; 11 abstracts were basic science studies and 183 were clinical studies. Altogether, 25 abstracts dealt with three-dimensional echocardiography, 15 with fetal echocardiography, 56 with deformation analysis, 79 with standard transthoracic echocardiography, and 19 were in the other category. A total of 73 abstracts were subsequently published - with a 37.6% publication rate - 2.1±1.7 years after initial presentation. There were no significant differences in publication rates based on the above-noted variables.
A paediatric cardiac echocardiography abstract publication rate of 37.6% is comparable to previous published publication rates for other meetings. No differences in variables analysed were noted between published versus unpublished abstracts.
在会议上以摘要形式展示科学信息对于传播新信息很重要。这些研究的发表应该是最终目标，但记录发表率的数据极少，尤其是关于儿科亚专业会议的。本研究的目的是记录儿科心脏超声心动图摘要的手稿发表率，并确定已发表和未发表的摘要之间是否存在差异。
回顾了2007年至2011年在美国超声心动图学会会议上展示的儿科心脏超声心动图摘要。记录了摘要的特征。使用关键词、第一作者和资深作者标准进行Medline/Pubmed搜索以确定发表情况。采用Fisher精确检验或χ2检验进行分析。
共审查了194篇摘要。其中，27篇为口头报告，167篇为海报展示。共有124篇摘要为前瞻性研究，70篇为回顾性研究；11篇为基础科学研究，183篇为临床研究。总共25篇摘要涉及三维超声心动图，15篇涉及胎儿超声心动图，56篇涉及变形分析，79篇涉及标准经胸超声心动图，19篇属于其他类别。共有73篇摘要随后发表，发表率为37.6%，首次展示后2.1±1.7年发表。基于上述变量，发表率没有显著差异。
儿科心脏超声心动图摘要37.6%的发表率与之前其他会议公布的发表率相当。已发表和未发表的摘要在分析的变量上没有差异。
