  • Conversion factors for units: calcium in mg/dl to mmol/L, ×0.25; phosphate in mg/dl to mmol/L, ×0.32; 25-hydroxycholecalciferol in ng/ml to nmol/L, ×2.5; calcitrol in pg/ml to pmol/L, ×2.6. No conversion necessary for alkaline phosphatase, osteocalcin, C-telopeptide, and iPTH. BMI, body mass index; iPTH, intact parathyroid hormone.

  • a Significant difference between patients with and without fracture (P < 0.05).

  • b Excluding corticosteroid use because of renal transplantation.
