The citation rate of a research published article is an indicator of its quality and impact and contributes to the journal's impact factor. Within the orthopaedic sports medicine literature, predictors of citation rates have not been previously described.
To identify characteristics of published articles that predict 5-year citation rates of studies in the orthopaedic sports medicine literature.
Cross-sectional study.
Research articles published in The American Journal of Sports Medicine (AJSM), Arthroscopy: The Journal of Arthroscopic and Related Surgery, and Knee Surgery, Sports Traumatology, Arthroscopy (KSSTA) from 2012 were analyzed. Extracted characteristics of published articles included journal, author number, origin of study, first author degree, subject of study, study type, sample size, number of references and institutions, conflicts of interest, level of evidence, and 5-year citation rates. Multivariate logistic regression was used to determine predictors of greater than the mean number of citations at 5 years.
A total of 825 published articles ( AJSM, n = 313; Arthroscopy, n = 173; KSSTA, n = 339) were included in the final analysis. The mean number of 5-year citations was 23.2 (95% CI, 21.6-24.9; range, 1.0-260.0). AJSM had a significantly greater citation rate (32.4) than Arthroscopy (21.7) and KSSTA (15.2) ( P < .001 for both). Arthroscopy had a greater citation rate than KSSTA ( P = .008). Independent predictors of greater than the mean number of citations at 5 years were published articles in AJSM (odds ratio [OR], 5.17; 95% CI, 2.81-9.52; P < .0001), published articles of North American origin (OR, 1.79; 95% CI, 1.25-2.58; P = .002), and published articles regarding the hip (OR, 2.68; 95% CI, 1.08-6.67; P = .035).
Published articles in AJSM, those from North America, and those examining the hip were independent predictors of greater citation rates at 5 years.
研究论文的引用率是其质量和影响力的指标，有助于提高期刊的影响因子。在矫形运动医学文献中，尚未描述过预测引用率的因素。
确定可预测矫形运动医学文献中研究论文 5 年引用率的发表文章特征。
横断面研究。
分析了 2012 年发表在《美国运动医学杂志》（AJSM）、《关节镜：关节镜与相关手术杂志》和《膝关节外科、运动创伤学与关节镜》（KSSTA）上的研究文章。提取发表文章的特征包括期刊、作者数量、研究来源、第一作者学位、研究主题、研究类型、样本量、参考文献和机构数量、利益冲突、证据水平以及 5 年引用率。采用多变量逻辑回归确定 5 年引用率大于平均值的预测因素。
最终分析纳入了 825 篇发表文章（AJSM，n=313；关节镜，n=173；KSSTA，n=339）。5 年引用率的平均值为 23.2（95%CI，21.6-24.9；范围，1.0-260.0）。AJSM 的引用率明显高于关节镜（21.7）和 KSSTA（15.2）（均 P<.001）。关节镜的引用率高于 KSSTA（P=.008）。5 年引用率大于平均值的独立预测因素为 AJSM 发表的文章（比值比[OR]，5.17；95%CI，2.81-9.52；P<.0001）、北美来源的文章（OR，1.79；95%CI，1.25-2.58；P=.002）和研究髋关节的文章（OR，2.68；95%CI，1.08-6.67；P=.035）。
AJSM 发表的文章、来自北美的文章以及研究髋关节的文章是 5 年引用率较高的独立预测因素。
