Hi,
On Sept. 19, 2004, a news story was posted to the OCF news section about long-term use of NSAID's (non-steroidal anti-inflammatory drugs) reducing the risk of oral cancer.

Today, a follow up story was posted stating that the orginal study was based on 'invented' data. Apparently, the researcher, Jon Sudbo, a Norwegian cancer expert, made up data for at least 250 patients in a trial size of 908. You can read the details:

News like this makes me think that one should not over emphasize the results of any one study and that reports of breakthroughs need corroboration- Sheldon
