WHAT TYPE OF HORMONE THERAPY DID WOMEN IN THE ESTROGEN-ALONE STUDY TAKE?
Women who were assigned at random (by computer) to receive active hormones in this study were taking conjugated equine estrogens 0.625 mg each day (Premarin®). When WHI first began, this was the most commonly prescribed hormone replacement therapy in the United States for postmenopausal women without a uterus.
