What was measured

Bone mineral density was assessed by dual x-ray absorptiometry.

Analysis population: BMD Analysis Set: all participants with evaluable femoral neck BMD values at Baseline and Month 36

Groups in this outcome

Placebo

Participants randomized to receive the matching placebo subcutaneously (SC) once every 6 months (Q6M) in the double-blind phase. All participants continued to receive an approved non-steroidal aromatase inhibitor therapy.

Denosumab

Participants randomized to receive 60 mg denosumab SC once Q6M in the double-blind phase. All participants continued to receive an approved non-steroidal aromatase inhibitor therapy.
