Study DesignCross-sectional.ObjectiveTo identify predictors of manuscripts achieving 6-year citation rates higher than the mean in spine-specific literature.Summary Of Background DataAn article's citation rate demonstrates its contribution to academia and its quality. Predictors of citation rates have not yet been studied in spine-specific medical literature.MethodsThree leading spine-specific journals were identified by a weighted scoring system comparing various journal metrics. Research articles published in 2014 were evaluated from the following journals: Spine, European Spine Journal, and Journal of Neurosurgery: Spine. Article features analyzed included journal of origin, number of words in article title, author count, degree of first author, conflicts of interest, quantity of contributing academic institutions, country of origin, study topic, study design, level of evidence, sample size, reference count, and citation rate. Multivariate logistic regression was used to determine predictors of above average citation rate at 6 years following publication.ResultsThe final analysis included 1091 articles. Spine had a significantly higher citation rate than European Spine Journal (P = 0.0008); however, no significant differences were observed between Spine and Journal of Neurosurgery: Spine. Regression analysis demonstrated that studies originating in North America (OR:1.44, 95% CI:1.01-2.01, P = 0.04), those with 6 ≥ authors (OR:1.72, 95% CI:1.29-2.30, P < 0.001), sample size >100 (P < 0.001), prospective case series (OR: 2.67, 95% CI: 1.24-5.76), and retrospective case series (OR: 1.99, 95% CI: 1.07-3.73) were independent predictors of achieving above average 6-year citation rates.ConclusionSpine, European Spine Journal, and Journal of Neurosurgery: Spine had the highest 6-year citation rates of the top 10 orthopedic spine journals, with Spine being significantly higher than European Spine Journal. Studies originating in North America, those with six or more authors, sample sizes > 100, and those that are retrospective or prospective case series are independent predictors of greater citation rates at 6 years in orthopedic spine-specific medical literature.Level of Evidence: 4.Copyright © 2021 Wolters Kluwer Health, Inc.
