从PubMed 1995年至2000年间对370篇出版物的搜索中,随机选择了16篇论文,由同一位作者完成。两篇论文几乎完全相同,只是导言段落和作者名单的形式不同。两份出版物都不承认对方。另一篇论文报道了“第二个发表的案例”,随后的两篇论文报道了同一个“第二个”案例,没有提及先前发表的论文。课文也很相似。

A randomised controlled trial submitted to a journal showed that a nutritional supplement could dramatically improve one aspect of the health of the elderly. The study was a follow up to a trial reported in an international journal eight years previously. Why had there been so much delay? Why were the results reported in this study not reported in the previous study? There was only one author and, if true, the results were extremely dramatic. The paper was sent for statistical review.

对一组相对较新的药物的有效性进行了系统综述。这项审查最初是为一个独立机构进行的,因此提交的是一份删节本。一位评论员指出,这篇评论没有提及Cochrane的评论和它引用的试验,这些评论是在论文提交给《华尔街日报》之前大约四个月发表的。

在发表了一份来自同一作者的随机对照试验后,收到了一封信,信中的通讯员暗示最初的试验可能是欺诈性的。首先,作者声称只有一位作者能够进行前瞻性、随机、双盲、安慰剂对照试验的可能性很小,尤其是在一家小型地区医院。记者还担心没有提及其他标准治疗方法。

案例

有矛盾数据的重叠论文

00-02

Three papers concerning one hospital problem had been submitted to three different journals. Before publication the three editors of the journals became aware of the three different papers and the substantial overlap between them. The three editors communicated with each other and realised that they had four concerns: 1. There was very considerable overlap among the three papers. There didn’t seem to be any justification for publishing three papers rather than one or two. 2.
