Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Increase in cortical and trabecular volumetric bone mineral density (vBMD) at the radius and tibia, assessed using peripheral quantitative computed tomography (pQCT). Added 25/01/2010: All outcomes were measured at baseline and 12 months after completing 12 months supplementation. | — |
Secondary
| Measure | Time frame |
|---|---|
| Changes in: 1. Bone geometry at the radius and tibia 2. Lumbar spine 3. Whole body measurements Assessed using peripheral quantitative computed tomography (pQCT) (distal and diaphyseal radius and tibia) and dual energy X-ray absorptiometry (DXA) (lumbar spine and whole body). Added 25/01/2010: All outcomes were measured at baseline and 12 months after completing 12 months supplementation. | — |
