Figure 4

Serum phosphorus values in patients with pre-transplantation fibroblast growth factor 23 (FGF23) concentrations below the median value (closed bars) as compared to patients with pre-transplantation FGF23 values above the median (open bars). The shaded area represents the normal range. Serum phosphorus concentrations decreased over time (p<0.01) with a greater decline in patients with higher pre-transplantation FGF23 concentrations (p<0.001 for the interaction between time and pre-transplantation FGF23).
