RT Journal Article SR Electronic T1 The Women’s Health Initiative: Implications for clinicians JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 385 OP 390 VO 75 IS 5 A1 Van Horn, Linda A1 Manson, JoAnn E. YR 2008 UL http://www.ccjm.org/content/75/5/385.abstract AB The Women’s Health Initiative (WHI), the largest and longest randomized controlled study to date of the effect of dietary change on disease outcomes in postmenopausal women, failed to show that a low-fat diet prevents breast cancer, colon cancer, or cardiovascular disease. However, as the authors point out, the WHI Extension Study provides opportunities to assess whether nearly significant differences in breast cancer rates at 8 years become significant after 10 years of follow-up.
