MSFinals-1718
A prospective study is designed to compare the risks and benefits of combined oestrogen and progesterone replacement therapy versus oestrogen-only replacement therapy in patients aged < 55 years, who are within 10 years of their menopause. One group of women will receive systemic oestrogen and progesterone for 4 years (HRT group) and the second group will receive the same systemic dose of oestrogen (without progesterone) for the same period (ERT group). The levonorgestrel intrauterine system is placed in women of the second group to counterbalance the effect of systemic oestrogen on the endometrium. The study will only include women who have not undergone a hysterectomy.
Which one of the following outcomes is most likely to be observed at the end of this study?
