The objectives of this study were to determine the degree of citation skew in otolaryngology journals and how article citation distribution affects their impact factors (IFs). Forty-one "otorhinolaryngology" journals in the Clarivate Journal Citation Reports database were identified and their article citation data from 2017 to 2020 extracted. Article citation frequency was remarkably similar across most journals, consistent with the narrow distribution of IFs (mean [SD], 1.9 [0.9]). Although the percentage of a journal's articles cited more than its IF during the IF citation window (mean [SD] of 32.4% [7.9%] of journals' articles)-reflecting citation skew-was not correlated with IF, the percentage of a journal's articles that were cited at least once (mean [SD] of 62.5% [15.3%] of articles) was highly correlated (ρ = 0.92, P < .001) with its IF. Although citation skew exists, otolaryngology journals' overall portfolios of published works-not a small number of highly cited articles causing citation skew-likely predominate their IFs.
本研究旨在确定耳鼻喉科期刊的引文偏倚程度，以及文章引文分布如何影响其影响因子（IF）。在科睿唯安期刊引证报告数据库中确定了 41 种“耳鼻喉科学”期刊，并提取了其 2017 年至 2020 年的文章引文数据。大多数期刊的文章引文频率非常相似，与 IFs 的狭窄分布一致（平均值[标准差]，1.9[0.9]）。虽然在 IF 引文窗口期间（32.4%[7.9%]的期刊文章），一个期刊的文章中超过其 IF 的引文比例（表示引文偏倚）与 IF 没有相关性，但一个期刊的文章中至少被引用一次的比例（62.5%[15.3%]的文章）与 IF 呈高度相关（ρ=0.92，P<.001）。尽管存在引文偏倚，但耳鼻喉科期刊发表的整体作品组合（而不是少数高被引文章导致的引文偏倚）可能主导着它们的 IF。
