When errors are identified in published articles, the publisher will consider what action is required and may consult the editors and the authors’ institution (s). Errors by the authors may be corrected by a corrigendum and errors by the publisher by an erratum. If there are errors that significantly affect the conclusions or there is evidence of misconduct, this may require retraction following the COPE Retraction Guidelines. All authors will be asked to agree to the content of the notice.
