One third of medical studies don't hold up

I just read over at CNN that some researchers investigated 45 highly publicized studies published in three major medical journals between 1990 and 2003.

Subsequent research contradicted results of seven studies -- 16 percent -- and reported weaker results for seven others, an additional 16 percent.

That means nearly one-third of the original results did not hold up, according to the report in Wednesday's Journal of the American Medical Association.

Interesting.
