- BMD: Bone mineral density
- BMC: Bone mineral content
- LS: Lumbar spine TH: Total hip FN: Femoral neck TR: Trochanter
- OC: Osteocalcin
- ucOC: Undercarboxylated osteocalcin
- TRACP-5b: Tartrate resistant acid phosphatase isoenzyme 5b
- Values of bone densitometric measures represent mean ± SD.
- OC values represent median with interquartile limits in parentheses.
- ucOC and TRACP-5b values represent geometric mean with values for M-SD and M+SD in parentheses.
- Bone densitometric data at the spine and at the hip were obtained from 1916 and 2008 participants, respectively, without severe deformities in the region of interest.
- Number of participants with available measurements for OC, ucOC and TRACP-5b were 1971, 1970 and 2003, respectively.
