Creatinine-Based Estimations of Kidney Function Are Unreliable in Obese Kidney Donors

Table 3

Performance of 24-hour creatinine clearance.

	Bias (mL/min/1.73 m^2)	IQR (mL/min/1.73 m^2)	P30
Normal; (BMI < 30) (𝑛=9)	23.6±9.2	38.8	22%
Class I Obesity (BMI 30–35) (𝑛=8)	17.8±6.5	23.9	75%
Class II/III Obesity (BMI > 35) (𝑛=7)	6.1±4.2	10.0	86%

Abbreviations: Bias—(measured GF-estimated GFR); IQR—interquartile range; BMI—body mass index (kg/m²); P30—percentage of estimated readings within 30 percent of measured readings.
