Richard Smith: The hypocrisy of medical journals over transparency – The BMJ

"We know that the commitment to transparency is less than complete in that most of the journals do not have open peer review and either don’t allow scientific studies to be open access or have systems as Byzantine as mobile phone contracts, making it easier to extract maximum payments from confused authors. But what we didn’t know until this week is the hypocrisy in relation to studies funded by commercial organisations, usually pharmaceutical companies. Despite repeatedly calling on pharmaceutical companies to make all their clinical trial results fully available, they put a block in the way."
