Peter C. Gøtzsche (born 26 November 1949) is a Danish physician, medical researcher, and leader of the Nordic Cochrane Center at Rigshospitalet in Copenhagen, Denmark. He co-founded, and 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 have 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]

Gøtzsche has commented on meta-analysis,[7] and the editorial independence of medical journals.[8] He has written about issues surrounding medical ghostwriting with the position that it is scientific misconduct.[9] He has also criticized the widespread use of SSRI antidepressants.[10]

Critique of mammography screening

Gøtzsche has been critical of screening for breast cancer using mammography, arguing that it cannot be justified; his critique has caused controversy.[11] His critique stems from a meta-analysis he did on mammography screening studies and published as Is screening for breast cancer with mammography justifiable? in The Lancet in 2000.[12] In it he discarded 6 out of 8 studies arguing their randomization was inadequate.

In 2006 a paper by Gøtzsche on mammography screening was electronically published in the European Journal of Cancer ahead of print.[13] The journal later removed the paper completely from the journal website without any formal retraction.[14] The paper was later published in Danish Medical Bulletin with a short note from the editor,[15] and Gøtzsche and his coauthors commented on the unilateral retraction that the authors were not involved in.[16]

In 2012 his book Mammography Screening: Truth, Lies and Controversy was published.[17] In 2013 his book Deadly Medicines and Organised Crime: How Big Pharma has Corrupted Healthcare was published.[18]
