The diagnosticvalue of TNF-α, IL-2, IL-6, and NGAL in patients with CSA-AKI wasevaluated by the size of the area under the curve (AUC = 0.9315, 95% confidenceinterval [CI] = 0.8831 to 0.9799) of the ROC curve, the ideal cutoff value, andthe corresponding sensitivity and specificity. Here, TNF is linked to acute kidney injury.
