A study published last week in The British Medical Journal
found that the results of nearly 30% of large randomized clinical studies were never published, and so their results aren't available to the public.
Senior author, Dr. Timothy Platts-Mills
, says that his research targeted studies that included more than 500 subjects because those studies are costly to conduct (about $10,000 per person involved). He says the non-publication of those costly studies was more likely to have been the result of a conscious decision, than of negligence. He worries that not publishing results can be harmful to the participants, and others looking to benefit from potential treatments and drugs.
