Number of biomarkers elevated higher than the cutoff values and the risk of developing acute kidney injury within 48 hours: (A) patients with creatinine levels <1.24 mg/dL; (B) patients with creatinine level ≥1.24 mg/dL.

<p>Regardless of the creatinine level on admission, elevation of ≥2 of the biomarkers higher than the cutoff values provided incremental value in risk stratification of acute kidney injury.
