OBJECTIVE
The overall aim of the present study was to compare the coverage of existing research funding information for articles indexed in Scopus, Web of Science, and PubMed databases.
METHODS
The numbers of articles with funding information published in 2015 were identified in the three selected databases and compared using bibliometric analysis of a sample of twenty-eight prestigious medical journals.
RESULTS
Frequency analysis of the number of articles with funding information showed statistically significant differences between Scopus, Web of Science, and PubMed databases. The largest proportion of articles with funding information was found in Web of Science (29.0%), followed by PubMed (14.6%) and Scopus (7.7%).
CONCLUSION
The results show that coverage of funding information differs significantly among Scopus, Web of Science, and PubMed databases in a sample of the same medical journals. Moreover, we found that, currently, funding data in PubMed is more difficult to obtain and analyze compared with that in the other two databases.
目的
本研究的总体目标是比较Scopus、科学网和PubMed数据库中索引文章的现有研究资金信息覆盖率。
方法
在三个选定数据库中识别2015年发表的带有资金信息的文章数量，并使用对28种著名医学期刊样本的文献计量分析进行比较。
结果
对带有资金信息文章数量的频率分析显示，Scopus、科学网和PubMed数据库之间存在统计学上的显著差异。科学网中带有资金信息的文章比例最高（29.0%），其次是PubMed（14.6%）和Scopus（7.7%）。
结论
结果表明，在同一医学期刊样本中，Scopus、科学网和PubMed数据库的资金信息覆盖率存在显著差异。此外，我们发现，目前与其他两个数据库相比，PubMed中的资金数据更难获取和分析。
