Data are presented as value, or value (95% CI). P value < 0.05 was considered to indicate a statistically significant difference (highlighted in bold).

BMD, bone mineral density; β, regression coefficient; β-CTX, β-C-terminal telopeptide of type I collagen; CI, confidence interval; LS, lumbar spine; N-NID, N-terminal middle segment osteocalcin; OR, odds ratio; P1NP, propeptide of type I procollagen; SE, standard error.
