Peter C. Gøtzsche is a Danish medical researcher, and leader of the Nordic Cochrane Center at Rigshospitalet in Copenhagen, Denmark. He has written numerous reviews within the Cochrane collaboration.
Among his research findings are that placebo has surprisingly little effect[1][2][3] and that many meta-analyses may suffer from data extraction errors.[4] Gøtzsche and his coauthors have been keen to criticize the research methods and interpretations of other scientists, e.g., in meta-analysis of placebo.[5][6]
His study of the efficiency of mammography drew much attention.[7]
In 2006 a paper of his was electronically "published" in the European Journal of Cancer ahead of print.[8] The journal later removed the paper completely from the journal web-site without any formal retraction.[9] The paper was later published in Danish Medical Bulletin with a short note from the editor,[10] and Gøtzsche and his coauthors commented on the unilateral retraction that the authors were not involved in.[11]
Gøtzsche has also commented on meta-analysis,[12] the editorial independence of medical journals[13] and medical ghostwriting.[14]
