Brief Summary
The purpose of this study is to learn about how the commonly used menopausal hormone therapies were prescribed and taken in practice. This is done by using healthcare database, to study the overall dangers and benefits of menopausal hormone therapies in real-world practice. This study will include subjects who were newly diagnosed menopausal symptoms between 2012 and 2019. They were all followed up for 12 months at least. The study included the below subjects who:
- were aged 40-59 years
- were diagnosed to have menopausal symptoms through some medical check-ups The data collected will be used to understand:
