Figure 1From: Cystatin C and beta2-microglobulin: markers of glomerular filtration in critically ill childrenReceiver operating characteristic curves to diagnose creatinine clearance of less than 80 ml/minute per 1.73 m2. Areas under the curve (95% confidence intervals) are 0.633 (0.403 to 0.863) for creatinine, 0.851 (0.698 to 1.003) for cystatin C, and 0.802 (0.628 to 0.976) for beta2-microglobulin (B2M).Back to article page
