Peter C. Gøtzsche
Peter C. Gøtzsche[pronunciation?] is a Danish physician, medical researcher, and leader of the Nordic Cochrane Center at Rigshospitalet in Copenhagen, Denmark. He co-founded and has has written numerous reviews within the Cochrane collaboration.
Among his research findings are that placebo has surprisingly little effect and that many meta-analyses may suffer from data extraction errors. Gøtzsche and his coauthors have been keen to criticize the research methods and interpretations of other scientists, e.g. in meta-analysis of placebo. Gøtzsche has also commented on meta-analysis, the editorial independence of medical journals and medical ghostwriting. He has also criticized the widespread use of SSRI antidepressants.
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. 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. 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. The journal later removed the paper completely from the journal website 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.
In 2012 his book Mammography Screening: Truth, Lies and Controversy was published. In 2013 his book Deadly Medicines and Organised Crime: How Big Pharma has Corrupted Healthcare was published.
