Menopausal hormone therapy in women linked to higher rates of dementia

I wish I was smart enough to dissect studies like this. What is the mortality rate between hypogonadal women who receive versus don’t receive HRT? Was hypogonadism controlled for? Is it just as easy to say hypogonadal women have increased mortality? I don’t know, 74% is a higher rate than smoking, is HRT more dangerous than smoking? is this an actual risk reduction, or relative risk reduction.

Maybe people are supposed to age without trying to cure it with drugs.
