14 vs. 0.031) were higher in CKD than in normal renal function. In subjects with 25(OH)D12 ng/mL, GFR was the only significant predictor in those with CKD (β-coefficient=-2.5, r=-0.55) and 25(OH)D was the only significant predictor in those with normal renal function (β-coefficient=-2.05, r=-0.11). Increasing age was associated with higher PTH levels only in those with normal renal function and 25(OH)D≥12 ng/mL. We showed that declining vitamin D and renal function have additive effects on serum PTH in subjects without vitamin D defic
