Key performance indicators (KPI) of eGFR equations in the whole dataset (n = 205). KPI evaluated were: median bias of eGFR to mGFR (A) and accuracy of eGFR measured as the percentage of samples with eGFR within 30% (P30) (B), 20% (P20) (C), and 15% (P15) (D) of mGFR. Error bars indicate bootstrapped 95% confidence interval (n = 1000). Dots represent the KPI of all data points. Each eGFR equation is represented by a different color, as indicated
