Figure 2: Receiver operator characteristic curves for prediction of acute kidney injury based on inverse of (a) estimated glomerular filtration rate and (b) serum albumin at baseline. The area under the curve for inverse of estimated glomerular filtration rate was 0.86 (95% confidence interval 0.76, 0.95); an estimated glomerular filtration rate threshold of 109.9 ml/min per 1.73 m^{2} had 76.0% sensitivity and 88.9% specificity for, and correctly classified 86.1% cases of acute kidney injury. The area under the curve for inverse of serum albumin was 0.67 (0.58, 0.78); serum albumin threshold of 1.20 g/dl had 58.3% sensitivity and 66.7% specificity, and correctly classified 64.9% cases of acute kidney injury
