Adjusted Percent Change From Baseline in Femoral Neck (FN) Bone Mineral Density (BMD) Via Dual-energy X-ray Absorptiometry (DXA) at Week 52
FN BMD (measured in grams per centimeters squared \[g/cm\^2\]) was measured by DXA. Bone mineral density is calculated as the mineral content of a bone divided by the area of the bone. DXA is the principal technique used for measuring BMD. Percent change from Baseline at Week 52 was calculated as (BMD at Week 52 minus BMD at Baseline)/BMD at Baseline x 100% and was assessed by analysis of covariance (ANCOVA) with terms for treatment, baseline value, prior therapy, and region. Change in FN BMD at Week 52 was only analyzed within the Rosiglitazone arm.
Time frame: Baseline and Week 52
