A large body of observational epidemiologic study has demonstrated that individuals who eat more fruits and vegetables rich in carotenoids and/or who have higher levels of serum betacarotene have a lower risk of cancer, particularly lung cancer. This inverse relationship has been(More)

Whereas one study reported no association, the other reported a significantly higher risk for vertebral and rib fractures among warfarin users compared with nonusers. The effect of vitamin K antagonists on age-related(More)
