Elevated Plasma Neutrophil Gelatinase-Associated Lipocalin Level as a Risk Factor for Anemia in Patients with Systemic Inflammation

Figure 3

ROC curves showing the diagnostic abilities of NGAL, hsCRP, and cESR to identify anemia in patients with systemic inflammation (n = 187). Area under the curve was calculated for cESR (AUC, 0.751; 95% CI, 0.674–0.836; sensitivity 79.5% and specificity 73.2% at the optimal cutoff of 25 mm/h), NGAL (AUC, 0.712; 95% CI, 0.618–0.787; sensitivity 58.3% and specificity 81.4% at the optimal cutoff of 156 ng/mL), and hsCRP (AUC, 0.649; 95% CI, 0.573–0.744; sensitivity 63.2% and specificity 57.6% at the optimal cutoff of 2.05 mg/dL).
