Some 15 years ago, 3 weeks into her tenure as the first female director of the National Institutes of Health, Bernadine Healy, MD, announced to Congress plans for a new and holistic study: the Women's Health Initiative (WHI). Hopes were high for the ambitious project. The largest randomized controlled trial (RCT) in history, costing the government an estimated $700 million, was expected to provide definitive answers to three key questions in women's health: (i) whether hormone replacement therapy (HRT) reduces the risk of heart disease, (ii) whether a high fat consumption increases the incidence of breast cancer, and (iii) whether calcium and vitamin D supplements prevent fractures.
The main results for all three trial arms have now been released.14 The outcome of the mega-trial including more than 50 000 postmenopausal women randomized to one, two, or three of the factorial trials has left consumers confused and timid and doctors puzzled.
