2. Figure 1
Mean (95% CI) serum parathyroid hormone (PTH; A) and calcitriol (B) levels in patients with different vitamin D receptor (VDR) genotypes and mild, moderate and severe chronic renal failure (CRF). The significant interaction between genotype and creatinine clearance (CCr) group leads to a significant increment of PTH levels the bb and Bb genotypes, but not in the BB genotype. Inversely, calcitriol levels are higher in the BB genotype than in the other genotypes in the mild and severe CRF groups. Symbols are: (□) mild CRF group; (⋄) moderate CRF group; (○) severe CRF group.
