here is the first article I read
Swedish study

I have been trying to find trials since the in USA.

I loved the Qol (‘quality of life’) statistic which looks optimistic - eg- don’t want worsening as some prescription drugs (like forteo) to help bone development can unfortunately have for patients.

Also, what we are wanting is fracture reduction- whole purpose of treatment- so I view this as more important than bone density itself

Anyway- lots of room for further research
