Of nan 876,805 women included successful nan main analysis, 104,086 (11.9%) redeemed a medicine for menopausal hormone therapy, and 47,594 (5.4%) died. By nan extremity of nan follow-up period, nan median long of menopausal hormone therapy usage was 1.7 years, pinch 41,433 (4.7%) women utilizing it for little than 1 year, and only 7,337 (0.8%) women reporting 10 aliases much years of use.

When not considering influential factors, nan consequence of all-cause decease for women pinch past aliases coming usage of menopausal hormone therapy was 54.9 deaths per 10,000 personification years compared pinch 35.5 deaths per 10,000 for women who had ne'er utilized it.

Investigating nan long of usage revealed nary accrued consequence of death, moreover aft 10 aliases much years of use. And no unequivocal differences were recovered betwixt nan groups for circumstantial causes of death, specified arsenic bosom disease, changeable aliases cancer.

What's more, women who had undergone bilateral oophorectomy aged 45 to 54 for non-cancerous reasons knowledgeable a important endurance use erstwhile utilizing menopausal hormone therapy, corresponding to a 27-34% little consequence of decease than women successful nan aforesaid group who did not usage hormone therapy.
