Study Endpoints
Primary Endpoints
Percentage of Participants With New Vertebral Fractures Through Month 36
Baseline through Month 36

New vertebral fracture: decrease in anterior, mid, or posterior vertebral (vt) height of approximately 20% and 4 millimeter (mm) or more from baseline (base) to end of study confirmed by measurement of involved vt body, a semi-quantitative grade change of 1 from base for any vertebra from fourth thoracic to fourth lumbar vertebra (T4 to L4), provided vertebra was not fractured at base. Participant was counted only once irrespective of how many new vt fractures were diagnosed. Stratification factor was base fracture status, categorized as no prevalent fracture and at least 1 prevalent fracture.

Percentage of Participants With New Vertebral Fractures Through Month 60
Baseline through Month 60

New vertebral fracture: decrease in anterior, mid, or posterior vt height of approximately 20% and 4 millimeter (mm) or more from baseline (base) to end of study confirmed by measurement of involved vt body, a semi-quantitative grade change of 1 from base for any vertebra from fourth thoracic to fourth lumbar vertebra (T4 to L4), provided vertebra was not fractured at base. Participant was counted only once irrespective of how many new vt fractures were diagnosed. Stratification factor was base fracture status, categorized as no prevalent fracture and at least 1 prevalent fracture.

Percentage of Participants With New Vertebral Fractures Through Month 84
Baseline through Month 84

New vertebral fracture: decrease in anterior, mid, or posterior vt height of approximately 20% and 4 millimeter (mm) or more from baseline (base) to end of study confirmed by measurement of involved vt body, a semi-quantitative grade change of 1 from base for any vertebra from fourth thoracic to fourth lumbar vertebra (T4 to L4), provided vertebra was not fractured at base. Participant was counted only once irrespective of how many new vt fractures were diagnosed. Stratification factor was base fracture status, categorized as no prevalent fracture and at least 1 prevalent fracture.
