Bias (systematic deviation) (a) and P30 (accuracy within 30%) (b) according to age for the CKD-EPI (ASR), CKD-EPI (AS), and EKFC equations in the BIS data (n = 570) a) The gray shaded area indicates a systematic deviation (bias) of 0–5 mL/min/1,73 m². b) The gray shaded area indicates the part where the P30 value is more than 75 %. Bias is defined as “eGFR minus mGFR”. P30 is defined as the percentage of the eGFR values within +/- 30% of mGFR and reflects the accuracy of the GFR estimation equation.
