Combined estrogen plus progestin therapy significantly reduces the risk of hip fractures and colorectal cancer in postmenopausal women.

While estrogen plus progestin therapy does reduce the risk of hip fractures and colorectal cancer, these benefits are not sufficient to justify the use of the therapy for primary prevention of chronic diseases due to the increased risks of heart disease, stroke, blood clots, and breast cancer.

Hip fracture, 0.66 (0.45-0.98)... Colorectal cancer, 0.63 (0.43-0.92)... absolute risk reductions per 10000 person-years were 6 fewer colorectal cancers and 5 fewer hip fractures.
