@rjd I'm not certain which were the most helpful but here are some I saved on my pc so I probably thought they were pretty good.

"Bone turnover is adequately suppressed in osteoporotic patients treated with bisphosphonates in daily practice" . The title says it all.
https://pmc.ncbi.nlm.nih.gov/articles/PMC3146915/
A good primer on bone markers:
"Bone turnover markers"
https://www.racgp.org.au/getattachment/a700d896-e591-42aa-a4cb-5b4575e77b7d/Bone-turnover-markers.aspx
This one is more difficult to follow but maybe worthwhile. I see I went thru it highlighting and making comments.
"Systematic review of the use of bone turnover markers for monitoring the response to osteoporosis treatment: the secondary prevention of fractures, and primary prevention of fractures in high-risk groups."
https://www.ncbi.nlm.nih.gov/books/NBK261650/
This one is long and technical:
"Bone Turnover Markers: Basic Biology to Clinical
Applications"
https://academic.oup.com/edrv/article/44/3/417/6889555
This one has a useful chart showing degree of suppression of CTX with different meds. It is an old paper so not all meds are covered:
" Bone turnover markers: use in osteoporosis" By Kim Naylor and Richard Eastell
I think I had to use Sci Hub to get the full pdf on this one.

This one is a from a webinar by Richard Eastell and is much more recent than the previous one, it's from 2019.
"Bone Turnover Markers For Monitoring Treatment of Osteoporosis"
I think I downloaded the slides here. I also see other webinars on bone markers on this same web page that I haven't looked at. Whether or not the complete webinars are available on Youtube or elsewhere I'm not sure?

Ok, I've got a lot more entries in my folder on bone markers but this is all I've got time for going thru.
Good luck and let us know what you find of interest.
