To predict all stages of AKI defined by any diagnostic criteria (KDIGO, AKIN, and RIFLE), the pooled AUC values of NGAL, L-FABP, IL-18, KIM-1, α-GST, normalised Cystatin-C, and normalised NAG are shown in Table 3, pooled AUCs for the identification of severe AKI cases are shown in Table 3. The gene discussed is IL18; the disease is acute kidney injury.
