This study aims to assess the impact of articles with very high reprint orders ("high-reprint articles") by measuring their citation in the subsequent literature as compared with a control group of articles.
The twenty-one articles (published in the Lancet in 1998) with reprint orders of over 10,000 were matched with a control set of twenty-one articles with smaller reprint orders. The Science Citation Index was used to obtain the number of citations for each of the forty-two articles.
The twenty-one high-reprint articles were cited 2,548 times; the mean number of citations was 121 (range, 3 to 499 citations per article). Five of the twenty-one high-reprint articles had more than 200 citations, but seven (33%) were cited twenty-five times or fewer. The twenty-one control articles were cited 986 times; the mean number of citations was forty-seven (range, 1 to 165). Fifteen (71%) of the twenty-one control articles were cited twenty-five times or fewer. Thirteen of the high-reprint articles were reports of randomized trials with a mean of 163 citations. In the control articles, six were reports of randomized trials with a mean of eighty-eight citations.
Articles with a high-reprint order were cited more frequently than other articles. However, some high-reprint articles were cited infrequently. If the size of a reprint order is related to the importance of an article, those articles with very high reprint orders may, therefore, be perceived as more important. Further research is needed to explore other aspects of the relative importance and impact of high-reprint articles.
本研究旨在通过测量“高重印量文章”（即重印订单量非常高的文章）在后续文献中的引用情况，并与对照组文章进行比较，以评估其影响。
将21篇（1998年发表于《柳叶刀》）重印订单量超过10000份的文章与21篇重印订单量较小的对照组文章进行匹配。使用科学引文索引获取这42篇文章各自的引用次数。
21篇高重印量文章被引用2548次；平均引用次数为121次（范围为每篇文章3至499次引用）。21篇高重印量文章中有5篇引用次数超过200次，但有7篇（33%）被引用25次或更少。21篇对照文章被引用986次；平均引用次数为47次（范围为1至165次）。21篇对照文章中有15篇（71%）被引用25次或更少。13篇高重印量文章是随机试验报告，平均引用次数为163次。在对照文章中，有6篇是随机试验报告，平均引用次数为88次。
高重印订单量的文章比其他文章被引用得更频繁。然而，一些高重印量文章被引用得很少。如果重印订单量的大小与文章的重要性相关，那么那些重印订单量非常高的文章可能会被认为更重要。需要进一步研究来探索高重印量文章相对重要性和影响的其他方面。
