Journal Retraction Rates and Citation Metrics: An Ouroboric Association?

Abstract

Introduction Retraction of published papers has a far-reaching impact on the scientific world, especially if the retracted papers were published in high-impact journals. Although it has been noted that the retraction rates of journals correlated with their citation metrics, no conclusive data were available for most clinical specialties. In this study, we determined the retraction rate for anesthesia and two comparison groups (neurosurgery and high impact clinical journals). We then studied the correlation of the retraction rate with citation metrics. Methods We generated a list of all anesthesia journals that were indexed in the National Library of Medicine database. We obtained the number of papers published in each journal as well as the number of papers retracted from each. We also collated the Impact Factor® and H-index of each journal. The same methodology was followed for neurosurgery and high impact clinical journals. We then studied the correlations between the retraction rate and citation metrics of each journal. Results The retraction index was 2.59 for anesthesiology, 0.66 for neurosurgery and 0.75 for the high-impact clinical journals group. The retraction rate did not correlate with the citation metrics. However, the number of papers published in each journal and the absolute number of retractions showed a positive correlation with the citation metrics. The H-index showed stronger correlations with these parameters than the Impact factor. Conclusions The number of retractions increased in proportion to both the number of papers published in a journal and the citation metrics of that journal.
