^aBMD Bone mineral density

^bSerum Ca Serum calcium

^cCT Calcitonin

^dPTH Parathyroid hormone

^ecOC Carboxylated osteocalcin

^fucOC Undercarboxylated osteocalcin

*Correlation is significant at P < 0.05

Note: The correlation is based on the 6 samples, n = 6/treatment, the tibia parameters were the average values of both sides
