Integrated biomarkers and renal Doppler for early acute kidney injury diagnosis in hepatitis C virus cirrhosis

Figure 5 Decision Tree for neutrophil gelatinase-associated lipocalin and renal resistive index-guided triage. Neutrophil gelatinase-associated lipocalin ≥ 150 ng/mL led to renal resistive index testing [≥ 0.74: Intensive care unit (ICU)-hepatorenal syndrome (39%); < 0.74: Conservative (48%); not done: ICU consider (13%)]. Neutrophil gelatinase-associated lipocalin < 150 ng/mL: High-risk to ICU (9%), low-risk to ward (25%), or conservative (6%). Prohibited pathways shown (0%). HRS: Hepatorenal syndrome; ICU: Intensive care unit; NGAL: Neutrophil gelatinase-associated lipocalin; RRI: Renal Resistive Index.
