Cystatin C is a biomarker for predicting acute kidney injury in patients with acute-on-chronic liver failure

Figure 3 Performance of four equations for measuring estimated glomerular filtration rate in patients with acute-on-chronic liver failure. A: Baseline estimated glomerular filtration rate (eGFR) between patients with or without acute kidney injury (AKI); B: Comparison of four eGFR values in patients with AKI. eGFR_CG: The Cockcroft and Gault formula; eGFR_MDRD: The modification of the diet in renal disease equation; eGFR_CysC-1: Cystatin C-based Hoek estimate; eGFR_CysC-2: Chronic Kidney Disease Epidemiology Collaboration cystatin C equation. ^bP < 0.01 vs GFRc_ysC in patients without AKI; ^dP < 0.01 vs e-GFR_CG, and e-GFR_MDRD in patients with AKI.
