Abstract

A detailed review of all 2,047 biomedical and life-science research articles indexed by PubMed as retracted on May 3, 2012 revealed that only 21.3% of retractions were attributable to error. In contrast, 67.4% of retractions were attributable to misconduct, including fraud or suspected fraud (43.4%), duplicate publication (14.2%), and plagiarism (9.8%). Incomplete, uninformative or misleading retraction announcements have led to a previous underestimation of the role of fraud in the ongoing retraction epidemic. The percentage of scientific articles retracted because of fraud has increased ∼10-fold since 1975. Retractions exhibit distinctive temporal and geographic patterns that may reveal underlying causes.

Relation of journal-impact factor to retractions for fraud or suspected fraud, error, and plagiarism, or duplicate publication. Journal-impact factor showed a highly significant correlation with the number of retractions for fraud or suspected fraud (A) (n = 889 articles in 324 journals, R2 = 0.08664, P < 0.0001) and error (B) (n = 437 articles in 218 journals, R2 = 0.1142, P < 0.0001), and a slight correlation with the number of retractions for plagiarism or duplicate publication (C) (n = 490 articles in 357 journals, R2 = 0.01420, P = 0.0243). The mean journal-impact factor of articles retracted because of fraud/suspected fraud or error was significantly different from that of papers retracted because of plagiarism or duplicate publication (D) (error bars ± SEM, P < 0.0001).

(A) Time-to-retraction as a function of year of retraction. R2 = 0.1236, P = 0.0414. (B) Time-to-retraction as a function of impact factor. Journal-impact factor correlated inversely with time-to-retraction for articles retracted because of fraud (n = 697, R2 = 0.01441, P = 0.0015) but not other causes.
