To determine if the quality of otolaryngology-related journal articles correlates with traditional measures of article impact.
All articles published by Laryngoscope in 2011 were categorized according to level of evidence (LOE) according to the Oxford Center for Evidence Based Medicine rubric. Articles without a level of evidence assigned were alphabetically subcategorized type with letters A-D corresponding to Contemporary Reports, Case Reports, Basic Science or Animal Studies, and Other respectively. Citations per article were then recorded per article each year from 2012 to 2018.
A total of 494 articles were included for analysis, 315 had numerical LOE and 179 had alphabetical LOE. There was a strong negative correlation between numerical LOE and median and interquartile number of citations ( = -.9014, = .037). Overall, numerical LOE had a significantly higher median number of citations per article compared with the non-number/alphabetical group (14 vs 6, < .001).
Higher quality research as determined by level of evidence is in fact being cited more frequently than lower quality articles. Although the scope of this study was relatively limited, these data suggest that better designed studies may exhibit greater impact by traditional measures. Such findings should serve as an impetus for (and validation of) continued pursuit of high LOE research.

确定耳鼻喉科相关期刊文章的质量是否与文章影响力的传统衡量指标相关。
根据牛津循证医学中心的标准，将《喉镜》2011年发表的所有文章按证据水平（LOE）进行分类。未指定证据水平的文章按字母顺序分为A - D类，分别对应当代报告、病例报告、基础科学或动物研究以及其他。然后记录每篇文章在2012年至2018年每年的被引次数。
共纳入494篇文章进行分析，315篇有数字形式的LOE，179篇有字母形式的LOE。数字形式的LOE与被引次数的中位数和四分位数间距之间存在很强的负相关性（ = -0.9014， = 0.037）。总体而言，与非数字/字母组相比，数字形式的LOE每篇文章的被引次数中位数显著更高（14对6， < 0.001）。
事实上，由证据水平确定的高质量研究比低质量文章被引用得更频繁。尽管本研究的范围相对有限，但这些数据表明，设计更好的研究可能在传统衡量指标上表现出更大的影响力。这些发现应为持续开展高LOE研究提供动力（并验证其合理性）。
无。
