Figure Lengend Snippet: Biochemical Parameters According to Primary Kidney Disease

Article Snippet: FGF23 concentrations were determined using a C‐terminal FGF23 ELISA kit (Quidel, San Diego, CA, USA), which detects both full‐length, intact FGF23 and C‐terminal FGF23 fragments (reference mean ± standard deviation [SD], 73 ± 38 RU/mL). ( ) Bone biopsy samples were obtained from the anterior iliac crest biopsy (2 cm below the anterior superior iliac spine) using a modified Bordier trephine needle, and therapy with active vitamin D sterols was discontinued for 4 weeks before the procedure, as previously described. ( ) Double tetracycline‐labeling was given (10 mg/kg/d for 2 days, followed by a 10‐day tetracycline‐free period, then a subsequent relabeling with 10 mg/kg/d for 2 days; the biopsy was performed 2 to 4 days after the last dose).
