Study Arms:
- Placebo (Type: PLACEBO_COMPARATOR): Participants received placebo subcutaneous injections every 4 weeks during the double-blind treatment phase. Participants then received open-label denosumab 120 mg by subcutaneous injection every 4 weeks during the open-label extension phase.
- Denosumb (Type: EXPERIMENTAL): Participants received 120 mg denosumab administered by subcutaneous injection every 4 weeks during the double-blind treatment phase. Participants then received open-label denosumab 120 mg by subcutaneous injection every 4 weeks during the open-label extension phase.

Based on this trial design, predict the completion outcome and termination type (if applicable).
