The dose was adjusted during follow-up to maintain serum total calcium between 8.0 and 9.5 mg\/dL. Serum calcium, phosphorus, 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D, 24-h urine calcium-to-creatinine ratio, and fractional excretion of phosphorus (FEPh) were measured at baseline and 6 months.

Age showed significant independent association with plasma FGF23 (\u03b2\u2005=\u20051.9, P\u2005=\u20050.001).
