VDD, vitamin D deficiency; R, vitamin D replacement. Diet protocol: IRI, standard diet for 120 days; VDD+IRI, vitamin D-free diet for 120 days; and VDD+IRI+R, vitamin D-free diet in the first 30 days and standard diet in the last 90 days. CIn, inulin clearance; BW, body weight; PUr, plasma urea concentration; MAP, mean arterial pressure; RBF, renal blood flow; RVR, renal vascular resistance; PAldo, plasma aldosterone concentration; P25(OH)D, plasma 25 hydroxyvitamin D concentration; PPTH, plasma parathormone concentration; PFGF−23, plasma fibroblast growth factor 23 concentration; FECa, fractional excretion of calcium; FEP, fractional excretion of phosphorus. Values are mean ± SEM. ap < 0.001, bp < 0.01, cp < 0.05 vs. IRI; dp < 0.001, ep < 0.01, fp < 0.05 vs. VDD+IRI.
