To analyze the trend of global peritoneal dialysis (PD) publications, especially of publications in Peritoneal Dialysis International (PDI), from 1991 to 2005 according to the Institute for Scientific Information databases of the Thomson Corporation.
Data were downloaded from the Web of Science, which includes the databases of Science Citation Index Expanded and Social Sciences Citation Index. The searching strategies were key-in of "peritoneal dialysis" in general search and of "SO=Peritoneal Dialysis International" in advanced search. Only articles and reviews were included in the analysis. The analysis was stratified by publication year, journal, author, country of each author's affiliation, and citation count of each paper.
There were 7618 PD papers (6991 articles and 627 reviews) in 887 journals; 15.8% of them (n = 1204) were published in PDI. The annual outputs of global PD publications has been more than 500 papers since 1996, with a peak of 665 articles in 2003. In total, 18531 authors from 102 countries and areas contributed to PD publications. Authors from the USA were present in 30.6% of all papers although their global share decreased with time. A PD paper received an average of 12.7 citations. A review received more citations than an article (17.0 vs 12.3 on average), yet statistical significance was not reached (p = 0.216, Mann-Whitney U test).
The number of PD research societies in the world has been growing during the past 15 years. More and more research is from countries other than the USA and the United Kingdom. Papers on PD have thus been published in many journals other than PDI, the leading journal in PD. However, the growth rate of PD publications in the world is diminishing. We present here the most likely reasons for the decrease in PD publications and propose suggestions for PDI to keep its leading role in the development of PD.
根据汤姆森公司的科学信息数据库，分析1991年至2005年全球腹膜透析（PD）出版物的趋势，尤其是《腹膜透析国际》（PDI）上的出版物趋势。
数据从科学网下载，该数据库包括科学引文索引扩展版和社会科学引文索引数据库。检索策略为在常规检索中输入“腹膜透析”，在高级检索中输入“SO=腹膜透析国际”。分析仅纳入文章和综述。分析按出版年份、期刊、作者、每位作者所属机构所在国家以及每篇论文的被引次数进行分层。
887种期刊上有7618篇PD论文（6991篇文章和627篇综述）；其中15.8%（n = 1204）发表于PDI。自1996年以来，全球PD出版物的年产量超过500篇，2003年达到665篇的峰值。来自102个国家和地区的18531位作者为PD出版物做出了贡献。美国作者出现在所有论文中的比例为30.6%，尽管其在全球的占比随时间下降。一篇PD论文平均被引12.7次。综述的被引次数多于文章（平均为17.0次对12.3次），但未达到统计学显著性（p = 0.216，曼-惠特尼U检验）。
在过去15年中，世界上PD研究学会的数量一直在增加。越来越多的研究来自美国和英国以外的国家。因此，除了PD领域的领先期刊PDI外，PD相关论文还发表在许多其他期刊上。然而，全球PD出版物的增长率正在下降。我们在此阐述PD出版物减少的最可能原因，并为PDI在PD发展中保持领先地位提出建议。
