Figure 1

Bland and Altman plots for glomerular filtration rate (GFR) estimated with different equations compared to measured GFR. Each graph is a Bland and Altman plot comparing a specific equation used for GFR estimation to the reference method (GFR measured using iohexol plasma clearance). Mean GFR is calculated as follows: Mean GFR = (measured GFR + estimated GFR)/2. The plain line represents the mean difference between estimated GFR (eGFR) and GFR measured using the reference method (mGFR). In the grey zone, eGFR is lower than mGFR. Dashed lines represent ± 1.96 SD. Results are expressed as mL/min/1.73 m2.
