Values are expressed as group mean ± 95% CI. p Value represents significant omnibus effect from RANCOVA. There was no group main effect for any of the DXA variables presented. Significant decrease from baseline for post hoc paired comparisons.
aBMD = areal bone mineral density; DFE = distal femoral epiphyses; DFM = distal femoral metaphysis; FN = femoral neck; PTE = proximal tibial epiphysis; TH = total hip.
