Ghost authorship

The undisclosed substantial contribution to a manuscript by a person not listed as an author or named in the acknowledgements. A contribution is ghost-written when, by ICMJE criteria, it would have warranted authorship had it been disclosed.

  • Not an instance

    A clinical-trial manuscript that names the medical writer in the acknowledgements with disclosure of their employer and the nature of their contribution.

Editorial commentary

Ghost authorship most often involves industry-funded medical writers who draft manuscripts later signed by named academic authors who contributed less substantively. It is distinct from declared professional medical-writing assistance, which is permitted under ICMJE and EMWA guidelines when fully disclosed. The Good Publication Practice (GPP3, now GPP 2022) framework provides industry-academia disclosure standards.
