This is a follow-up article to "Fate of Submitted Manuscripts Rejected from the American Journal of Neuroradiology: Outcomes and Commentary." The purpose of this study was to quantify differences in citation frequency between manuscripts published in the American Journal of Neuroradiology (AJNR) and those published after AJNR rejection and to understand citation frequency differences among rejected manuscripts.
In this study, a MEDLINE search identified all manuscripts published in AJNR in 2005 and those initially rejected by AJNR in 2004 but subsequently published elsewhere. Once identified, the citation frequencies of both groups were determined by using SCOPUS. Citation data were used in comparative studies between AJNR rejected and accepted articles and in studies comparing citation frequency differences among rejected manuscripts as a function of journal and/or publication classifications.
Among 315 subsequently published rejections from AJNR in 2004, 696 citations accumulated between 2005 and 2007 (2.4 citations/journal year), whereas 441 AJNR articles published in 2005 accumulated 2490 citations between 2005 and 2007 (6.4 citations/journal year, P < .0001). One-way analysis of variance suggested that rejected manuscripts classified as technical reports and/or published in journals classified as either neuroradiology or general radiology had significantly higher citation frequencies than other submission types and journal classifications. Nonparametric analysis of citation frequency showed significant correlations with impact factors of respective publishing journals (rho = 0.444).
Results from this study suggest that publications initially rejected from AJNR have a significantly lower citation frequency than those accepted by AJNR. Among rejected manuscripts, citations frequencies were highest in technical reports and among journals close to the neuroradiologic discipline.
本文是《美国神经放射学杂志退稿稿件的命运:结果与评论》的后续文章。本研究的目的是量化在美国神经放射学杂志(AJNR)上发表的稿件与AJNR退稿后在其他地方发表的稿件之间的引用频率差异,并了解退稿稿件之间的引用频率差异。
在本研究中,通过MEDLINE检索确定了2005年在AJNR上发表的所有稿件以及2004年最初被AJNR拒稿但随后在其他地方发表的稿件。确定这些稿件后,使用SCOPUS确定两组稿件的引用频率。引用数据用于AJNR退稿与录用文章之间的比较研究,以及比较退稿稿件之间因期刊和/或出版物分类而产生的引用频率差异的研究。
2004年AJNR退稿后随后发表的315篇稿件中,2005年至2007年期间累计有696次引用(每年每期刊2.4次引用),而2005年发表的441篇AJNR文章在2005年至2007年期间累计有2490次引用(每年每期刊6.4次引用,P <.0001)。单因素方差分析表明,归类为技术报告和/或发表在神经放射学或普通放射学类期刊上的退稿稿件的引用频率明显高于其他投稿类型和期刊分类。引用频率的非参数分析显示与各发表期刊的影响因子有显著相关性(rho = 0.444)。
本研究结果表明,最初被AJNR拒稿的出版物的引用频率明显低于被AJNR录用的出版物。在退稿稿件中,技术报告以及与神经放射学学科相近的期刊中的引用频率最高。
