2.11. Measurement of BMD and Serum OCN, Ca, and PTH Levels in Humans 
ADVERSE EVENTS, BLOOD
BMD was measured at baseline and after 24 weeks in the lumbar spine L1-L4 and left femoral total using a DXA (BHR-100-P IDXA, GE LUNAR, Madison, WI, USA). Bone health-related biomarkers such as OCN, Ca, and PTH were measured at baseline and 24 weeks. Blood pressure, pulse, and adverse events were measured and recorded at each visit to evaluate safety.
