Outcome Measures
Primary Outcome Measures
- The average rate of bone mineral density change of lumbar spine (L1-L4 ) was compared between 48 weeks after administration and before administration .the group of minodronate were examined and compared to that of alendronate. [48 weeks]
Secondary Outcome Measures
- The average rate of bone mineral density change of lumbar spine (L1-L4 ) was compared between 24 weeks after administration and before administration . [24weeks]
- The change rate of bone turnover markers from baseline to 12、24、48 weeks, including serum type I collagen amino terminal peptide(P1NP) and serum C-terminal telopeptide of type 1 collagen (S-CTX ). [12、24、48 weeks,]
- the change rates of bone density at the femoral neck and the whole hip from baseline to the end of 24 and 48 weeks. [24、48 weeks]
