Longitudinal assessment of measured and estimated glomerular filtration-rate in autosomal dominant polycystic kidney disease: Real practice experience

Figure 2 Bland-Almant plot of study sample. A: Bland-Almant plot of study sample comparing the measured glomerular filtration rate (mGFR) and the estimated glomerular filtrataion rate (eGFR) assessed by different formulas; B: Bland-Almant plot of study sample comparing the changes between baseline and month-6 mGFR and the eGFR assessed by different formulas. The mean score is plotted on the x-axis, and the difference between observers (mean of the differences) is plotted on the y-axis (mean difference ± 1.96 SD). Dark circles represent the patients with a baseline mGFR ≤ 80 mL/minute. The empty squares represent the patients with a baseline mGFR > 80 mL/minute. mGFR: Measured glomerular filtration rate.
