背景：期刊影响因子（JIF）指标是否反映了期刊在不同学科类别中平均一篇文章的被引用次数存在争议。我们试图进一步调查这个问题，在一般和内科journals.Methods：我们选择了上述主题类别的三个期刊进行评估，在三个不同的JIF水平（高：15.5-28.6，中等：4.4-4.9和低：1.6）。使用Scopus数据库，我们检索了2005年在选定期刊上发表的原始研究文章（经过详细筛选）和综述文章（由Scopus分类），沿着2006年和2007年收到的引用数量。我们汇集了相同类型的期刊文章的引用具有相同的JIF到不同的variables.Results：有没有显着的关联之间的分布，每篇文章发表在一般的医学期刊和他们的JIF。所有研究的分布都向右倾斜（引用次数较多）。具体而言，16-22%的原创研究文章占所有三类研究期刊此类文章总引用量的50%; 34-37%的原创研究文章占引用量的75%。结论：临床医学高、中、低影响因子期刊的引文分布相似。JIF并不能准确反映文章的平均引用量;在低影响因子期刊上发表的文章仍然可以被高引用，反之亦然。
Background:Whether the journal impact factor (JIF) indicator reflects the number of citations to an average article of a journal in different subject categories is controversial. We sought to further investigate this issue in general and internal medicine journals.Methods:We selected to evaluate three journals of the above subject category, in each of three different JIF levels (high: 15.5-28.6, moderate: 4.4-4.9 and low: 1.6). Using the Scopus database, we retrieved the original research articles (after detailed screening) and review articles (as classified by Scopus) that were published in the selected journals in 2005 along with the number of citations they received in 2006 and 2007. We pooled the citations for articles of the same type in journals with the same JIF level into distinct variables.Results:There was no marked association between the distribution of citations per article published in general medical journals and their JIF. All distributions studied were skewed to the right (higher number of citations). Specifically, 16-22% of the original research articles accounted for 50% of the total citations to this type of article for all three categories of studied journals; 34-37% of original research articles accounted for 75% of citations. The respective values for review articles were 12-18% and 29-39%.Conclusion:The distribution of citations received by articles published in high, moderate and low impact factor journals in clinical medicine seems similar. The JIF is not an accurate indicator of the citations the average article receives; articles published in low impact factor journals can still be highly cited and vice versa.
