CTX: Bone Resorption Marker

Lower values = less bone breakdown

3 Months EVENITY + 9 Months Prolia
12 Months EVENITY
0.50 0.40 0.30 0.20 0.10 0
Switch to Prolia
Baseline 3 mo 6 mo 12 mo
Key point: Prolia suppresses bone breakdown more powerfully than EVENITY. The 3-month group got stronger anti-resorption protection for 9 months, compensating for less time on EVENITY.
