A related editorial discusses this research. Overall, the results of these trials expand the understanding of the long-term risks and benefits of hormone therapy, an important issue for women around the world. The findings provide reassurance that there is no longterm increase in either all-cause or cause-specific mortality among women who received hormone therapy for up to 5.6 years (combination estrogen plus progestin hormone therapy group) or 7.2 years (estrogen-alone group). This information will be helpful in counseling women considering whether to start hormone therapy and hopefully will alleviate concerns that many patients and physicians have about the initiation of hormone therapy. For women with troubling vasomotor symptoms, premature menopause, or early-onset osteoporosis, hormone therapy appears to be both safe and efficacious.
