Figure 3. Agreement between estimated glomerular filtration rate (eGFR) methods, mean differences, and Bland‐Altman plots.

Above‐diagonal panels show the mean difference and the limit of agreement (±1.96 SD). Below‐diagonal panels show Bland‐Altman plots of the difference vs the mean of pairwise methods.
