The study, an analysis of a database of 1.4 million Kaiser Permanente members, found that those who took Vioxx were more likely to suffer a heart attack or sudden cardiac death than those who took Celebrex, Vioxx's main rival. Based on their findings, Graham and his collaborators linked Vioxx to more than 27,000 heart attacks or sudden cardiac deaths nationwide from the time it came on the market in 1999 through 2003.

Graham told the finance committee investigators that the FDA was trying to block publication of his findings, Grassley said in a statement. "Dr. Graham described an environment where he was 'ostracized,' 'subjected to veiled threats' and 'intimidation,' " Grassley said. Graham gave Grassley copies of e-mail that appear to support his claims that his superiors suggested watering down his conclusions.
