The unfortunately long life of some retracted biomedical research publications

Abstract

In 2005 the scientific misconduct case of a noted researcher concluded with, among other things, the retraction of 10 papers. However, these articles continue to be cited at relatively high rates. The objectives of this paper are: 1) to track the retraction process of these papers, 2) to assess the impact of retraction on subsequent citation rates of these papers, and 3) to compare the citation history of these retracted articles and five other high-profile retraction cases. For objective 1, all five articles to be retracted were retracted and of the four to be corrected, two were retracted and two were corrected. Eight PubMed and journal sites were identified where retraction messages could be conveyed; the number of retraction messages averaged 3.4 ± 2.5 for these nine articles. For objective 2, an absolute "cleansing" did not occur. While it initially appears there was a relative "cleansing," as citation rates for these articles did decrease after retraction, the reductions in citation rates for these articles (-28%) were the same as those for matched nonretracted publications both by the same author (-28%) and by another investigator (-29%) over the same time frame. Relative to objective 3, the results for this case are quite different from the five other cases assessing this issue, perhaps because of this investigator's "citation inertia" as a result of the small percentage of his papers that were retracted and the large number of citations to the articles before their retraction and to all of his published articles.NEW & NOTEWORTHY The scientific misconduct and fraud case of a noted exercise physiology researcher was concluded ~15 yr ago, and one the of the results was the retraction of 10 published manuscripts. However, based on a number of comparisons to that same author's and another investigator's citation histories for similar articles, the citation histories for these retracted articles appear to not have been affected whatsoever in the subsequent 15 yr.
