Abstract

BACKGROUND

Covert duplicate publication is unquestionably unethical and problematic. Approximately 3000 articles describing Budd-Chiari syndrome in China have been published. However, no study has yet explored the prevalence of covert duplicate publications among these articles.

METHODS

We retrieved original articles regarding Budd-Chiari syndrome in China via the PubMed, Chinese Scientific and Technological Journal (VIP), and China National Knowledge Infrastructure databases. The prevalence of covert duplicate publications was evaluated across publication dates, institutional grades, and academic levels of the journals.

RESULTS

Overall, 1914 articles were included in our analysis. These articles were produced by 632 institutions and published in 463 journals. Overall, 10% (184/1914) of the articles, 10% (62/632) of the institutions, and 26% (119/463) of the journals were involved in covert duplicate publications. A decreasing trend in the prevalence of covert duplicate publications over time was observed. The prevalence of covert duplicate publications was significantly higher in tertiary hospitals than in primary hospitals or unclassified institutions (10.0% vs 3.8%, P = .038), but the prevalence was similar between tertiary and secondary hospitals (10.0% vs 9.3%, P = .72). The prevalence of covert duplicate publications was significantly higher in Science Citation Index journals than in Chinese Academic Core journals (23.9% vs 10.3%, P = .001) and other journals (23.9% vs 8.3%, P < .001).

CONCLUSIONS

Covert duplicate publications are relatively common among articles on Budd-Chiari syndrome in China. The high prevalence of covert duplicate publication in Science Citation Index journals should remind English-language journal editors to verify whether the articles submitted by Chinese researchers have been published in Chinese-language journals.

摘要

背景

隐性重复发表无疑是不道德和有问题的。在中国已经发表了大约 3000 篇描述布加综合征的文章。然而，目前尚无研究探讨这些文章中隐性重复发表的流行情况。

方法

我们通过 PubMed、中国科技期刊数据库（VIP）和中国国家知识基础设施数据库检索中国布加综合征的原始文章。评估了出版物日期、机构等级和期刊学术水平对隐性重复发表的影响。

结果

总体而言，我们的分析共纳入了 1914 篇文章。这些文章来自 632 个机构，发表在 463 种期刊上。总体而言，10%（184/1914）的文章、10%（62/632）的机构和 26%（119/463）的期刊涉及隐性重复发表。随着时间的推移，隐性重复发表的比例呈下降趋势。三级医院隐性重复发表的比例明显高于一级医院或未分类机构（10.0%比 3.8%，P=0.038），但三级医院和二级医院之间的比例相似（10.0%比 9.3%，P=0.72）。科学引文索引期刊隐性重复发表的比例明显高于中文核心期刊（23.9%比 10.3%，P=0.001）和其他期刊（23.9%比 8.3%，P<0.001）。
