What were the main findings in the WHI study on estrogen-plus-progestin?
A. The main findings show that compared to women taking placebo pills: • The number of women who developed breast cancer was higher in women taking estrogen plus progestin. • The numbers of women who developed heart attacks, strokes, or blood clots in the lungs and legs were higher in women taking estrogen plus progestin. • The numbers of women who had hip and other fractures or colorectal cancer were lower in women taking estrogen plus progestin. • There were no differences in the number of women who had endometrial cancer (cancer of the lining of the uterus) or in the number of deaths.
