*Adjusted for serum albumin. PTH: parathyroid hormone; BAP: bone specific alkaline phosphate; DPD/Cr: deoxypyridinoline corrected for urinary creatinine concentration; NTx/Cr: cross-linked N-telopeptide of type 1 collagen corrected for urinary creatinine concentration; BSI: bone balance status index.
