Retractions related to fraud showed a more than sevenfold increase between 2004 and 2009, exceeding the twofold rise in retractions related to mere error, according to an analysis published in the Journal of Medical Ethics. The analyst, Grant Steen, reached that conclusion after studying 742 medicine and biology papers that were withdrawn from 2000 to 2010. He said 73.5% were retracted simply for error but 26.6% were retracted for fraud.
