Diagnostic measures of three different equations used to estimate glomerular filtration rate (GFR) using a cut-off of 60 ml/min/1.73m².

Diagnostic measures	Equations used to estimate GFR
	MDRD	CKD-EPI	FAS
AUC (95% CI)	0.86 (0.82, 0.89)*	0.87 (0.83, 0.91)	0.87 (0.84, 0.91)
Standard error	0.02	0.02	0.02
Sensitivity, %	84.11	80.37	89.72
Specificity, %	80.00	82.73	72.73
Youden	0.64	0.63	0.62

MDRD, Modification of Diet in Renal Disease equation, CKD-EPI, Chronic Kidney Disease Epidemiology Collaboration equation; FAS, full age spectrum; AUC, area under the curve; CI, confidence interval.
