His study of the efficiency of mammography drew much attention.
In 2006 a paper of his was electronically "published" in the European Journal of Cancer ahead of print. The journal later removed the paper completely from the journal web-site without any formal retraction. The paper was later published in Danish Medical Bulletin with a short note from the editor, and Gøtzsche and his coauthors commented on the unilateral retraction that the authors were not involved in.
Gøtzsche has also commented on the editorial independence of medical journals.
