Reliability of neutrophil gelatinase-associated lipocalin in detecting acute tubular necrosis in decompensated cirrhosis: Systematic review and meta-analysis

Figure 1 PRISMA flowchart detailing study selection.

Figure 2 Forest plot showing the association between the urine neutrophil gelatinase-associated lipocalin biomarker and acute tubular necrosis in hospitalized patients with cirrhosis. OR: Odds ratio; lcl: Lower confidence limit; ucl: Upper confidence limit; prob: Probability.

Figure 4 Forest plots demonstrating the neutrophil gelatinase-associated lipocalin predictiveness and mortality in decompensated cirrhosis patient with acute kidney injury. A: Forest plot showing the area under the curve for urine neutrophil gelatinase-associated lipocalin predictiveness of acute kidney injury in decompensated cirrhosis patients. The pooled estimate demonstrates the cumulative result of all the studies combined; B: Forest plot of the meta-analysis of mortality among decompensated cirrhosis patients with acute kidney injury across different studies. The lower diamond in the graph demonstrates the cumulative result of all the studies combined.
