Table 5 Performance characteristics of urinary interleukin-18 (IL-18) according to different network criteria of acute kidney injury

From: Urinary interleukin-18 does not predict acute kidney injury after adult cardiac surgery: a prospective observational cohort study

Variables AUC-ROCC (95% CI) P value
AKIN stage 1 or worse (n = 32)   
   Urinary IL-18 on arrival in the intensive care unit 0.48 (0.35–0.61) 0.80
   Urinary IL-18 at 24 hours after cardiopulmonary bypass 0.59 (0.46–0.72) 0.15
  1. Acute kidney injury defined according to the network criteria [15] with serum creatinine increase of greater than 26.4 μmol/L or greater than 0.3 mg/dL within 48 hours postoperatively. AKIN, Acute Kidney Injury Network; AUC-ROCC, area under the curve for the receiver operating characteristic curve; CI, confidence interval.
