Serum creatinine, age, sex, race	1.16	0.236	0.243
Serum creatinine, age, sex, race	1.16	(0.229 to 0.242)	(0.232 to 0.254)
Serum creatinine, age, sex	N/A	0.244	0.258
Serum creatinine, age, sex	N/A	(0.238 to 0.251)	(0.248 to 0.268)
Serum creatinine, age, race, sex, height, and weight	1.15	0.235	0.242
Serum creatinine, age, race, sex, height, and weight	1.15	(0.229 to 0.242)	(0.232 to 0.253)
Serum creatinine, age, sex, height, and weight	N/A	0.243	0.255
Serum creatinine, age, sex, height, and weight	N/A	(0.237 to 0.250)	(0.245 to 0.265)

^a Data are from the CKD-EPI pooled development datasets; ^b RMSE is the square root of the mean of squared differences between mGFR and eGFR; lower RMSE values indicate higher accuracy of the eGFR. 95% CI, 95% confidence interval.
