Table 4.
ARD | Overall (n = 40) | eGFR ≥ 20 mL/min/1.73 m2 (n = 28) | eGFR < 20 mL/min/1.73 m2 (n = 12) |
---|---|---|---|
Mean (SD) | 15.42 (14.44) | 12.80 (7.85) | 21.55 (23.02) |
Median (IQR) | 14.78 (7.38, 20.18) | 12.65 (6.37, 17.63) | 18.32 (12.94, 20.96) |
(Minimum, maximum) | (0.30, 91.00) | (0.30, 30.28) | (1.03, 91.00) |
Abbreviations: ARD = absolute relative difference; eGFR = estimated glomerular filtration rate; IQR = interquartile range.
Mean absolute relative difference has also been calculated in different chronic kidney disease strata (patients with eGFR of >20 mL/min/1.73 m2 and those with <20 mL/min/1.73 m2).
