Today, I (Peter Gøtzsche) discovered that an article I published in 2011 in the Cochrane Database of Systematic Reviews about review production in Cochrane no longer existed. I have therefore uploaded it. It showed that Cochrane centres were essential for review production. However, Cochrane’s CEO from 2012 to 2021, journalist Mark Wilson, systematically undermined the functions, reputation and the credibility of Cochrane centres to consolidate his grip on power – to such an extent that they from December 2018 no longer existed but were called “geographic groups” – which was management by stealth. I suspect the disappearance of my article is related to this.
