Total proximal femur bone mineral density relative to the young adult mean

Older age strata is associated with total proximal femur bone mineral density relative to the young adult mean in humans (13.8% lower at 80–89 years and 20.8% lower at ≥90 years versus 65–79 years).

“The young adult mean of the total proximal femur was significantly lower in Groups II and III than that in Group I by 13.8% and 20.8%, respectively.”
