Median SCr versus age (black curves) and reference limits (red curves) in healthy women and men [12] (left panels) converted to rescaled SCr/Q (right panels). The dots are the actual data from Pottel, et al. [12]. The median SCr concentration in the left panels corresponds to SCr/Q=1 in the right panels. The lower and upper limits in the left panels correspond to SCr/Q=0.67 and SCr/Q=1.33, respectively, in the right panels. Abbreviations: SCr, serum creatinine; SCr/Q, serum creatinine-to-Q value ratio.
