Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Hypothesis: Use of hormone replacement therapy (HRT) decreases the incidence of fractures in early postmenopausal women.

The project was initiated in 1990, and the inclusion ended in 1993. A total of 2,016 early postmenopausal women were divided into two groups: The first group accepted randomisation to HRT or not, and the second group was allowed to choose HRT or not.

The study was not blinded. Main measurements were fracture risk over 20 years, changes in bone mineral density over 20 years, and side effects, mainly breast cancer.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Aim: To study the ability of hormone replacement early after menopause on risk of fractures and changes in bone mineral density, and side effects.

The project was designed as a comprehensive cohort trial. One group accepted randomisation, and was randomised to hormone replacement therapy (HRT) or not (no placebo used).

502 were randomised to HRT, and 504 were randomised to no HRT) One group was allowed to choose HRT or not. A total of 221 chose HRT, and 789 chose no HRT.

First line HRT was oral sequential oestradiol/norethisterone in women with intact uterus and oral continuous oestradiol in hysterectomised women.

The study was initiated in 1990, and inclusion ended in 1993.
