Post-menopausal women who have higher estrogen levels as a result of taking hormone replacement therapy (HRT) may have a lower risk of death from COVID-19 than women with natural levels of the hormone, according to a new Swedish study.
The research, published February 14 in BMJ Open, also found that women who were taking estrogen-blocking therapy because of a previous breast cancer diagnosis were more than twice as likely to die; on the other hand, after researchers adjusted for several factors that could influence COVID-19 risk, the association was no longer statistically significant.
