CHICAGO (AP) - New research highlights a frustrating fact about science: What was good for you yesterday frequently will turn out to be not so great tomorrow.
The sobering conclusion came in a review of major studies published in three influential medical journals between 1990 and 2003, including 45 highly publicized studies that initially claimed a drug or other treatment worked.
Subsequent research contradicted results of seven studies — 16 percent — and reported weaker results for seven others, an additional 16 percent.
