The Women's Health Initiative is a randomized controlled clinical trial conducted in 40 clinical centers across the United States addressing some of the most common causes of death, disability, and impaired quality of life in postmenopausal women ages 50-79: cardiovascular disease; breast and colon cancer; and osteoporosis.
