If I'm using it right, it looks like more than 7.5 million papers were submitted to PubMed in this 10 year period. Only 0.01% of all papers were retracted and only 0.003% were retracted due to "fraud". This seems like an exceedingly small sample. I wish we could see more of the raw analysis (p-scores and the like).

I think the other result was more interesting: 53% of "faked" research papers were submitted by "repeat offenders", while only 18% of "erroneous" papers were. If you do this once it seems you are likely to do this again.

BTW, the abstract is at http://jme.bmj.com/content/early/2010/10/18/jme.2010.038125
