Table 3 Multiple linear regression analysis of markers of bone turnover and BMD T-scores at various skeletal sites

From: Age-related bone turnover markers and osteoporotic risk in native Chinese women

Bone turnover markers are identified as independent variables, while BMD T-scores at different skeletal sites are identified as dependent variables. Abbreviations: as in Table 1, R² C(%)-R square change. *P = 0.040–0.000. ^▲Marker was excluded from this analysis.
