The fate of scientific articles when errors and scientific misconduct are detected

: When a minor error is noted in a scientific article, the publishing journal should issue a correction. Issuing an expression of concern is relevant when scientific misconduct is suspected. If the suspicion proves to be well founded, the journal should retract the article. The number of retractions is increasing, and this emphasizes the need for unequivocal concepts and guidelines. The reason a given article is corrected or retracted should be unambiguous and articles as well as notices should be indexed properly.
