“In women in the WHI aged 50 to 59 years, CEE plus MPA (average, 5.6 years of use) or CEE alone (average, 7.2 years of use in women with previous hysterectomy) did not increase cancer mortality or CV mortality after a median of 18 years’ follow-up compared with placebo.” “In women aged 50 to 59 years at randomization, all-cause mortality was significantly reduced in the pooled trials versus placebo (HR, 0.69; 95% CI, 0.51-0.94). With age groups combined, breast cancer mortality was reduced in women using CEE alone (HR 0.55; 95% CI, 0.33-0.92), and Alzheimer disease or dementia mortality was reduced in women using CEE alone (HR, 0.74; 95% CI, 0.59-0.94) and in the pooled trials (HR, 0.85; 95% CI, 0.74-0.98) after a median of 18 years’ follow-up.” https://www.menopause.org/docs/default-source/professional/nams-2022-hormone-therapy- position-statement.pdf
