For the meta-analysis study, we chose lumber BMD, hip BMD, and BTM NTX as the outcome measures. Data on severe vertebral fractures, BTMs BALP, osteocalcin, NTX, and serum PINP were also extracted for summary and discussion. Original data collection forms were used to abstract the following information from single studies: sample size, dose, and changes from base line. Two reviewers screened articles independently, and disagreements were resolved through discussion. The Cochrane Collaboration’s tool was used to assess risk of bias.
