Figure 6. Population mean levels of mineral metabolites restricted to observations prior to initiation of phosphate binders and nutritional and active vitamin D.

Figure 6.

Cubic spline smoothed population mean levels (with 95% confidence intervals) in ln(FGF-23) (red), ln(PTH) (green), phosphate (blue), and calcium (orange) levels prior to ESRD transition. Shaded areas represent 95% confidence intervals. The table below the plot depicts the number of participants with available measurements of FGF-23, PTH, phosphate, and calcium by years prior to ESRD transition. Repeated measures values are shown as median (interquartile range) for FGF-23 and PTH and mean ± standard deviation for phosphate and calcium.
