FABP2 and Cirrhosis: Plasma levels of FABPs were significantly higher in patients with ACLF compared to those of patients with decompensated cirrhosis without ACLF [A-FABP4: (67 (43–106) vs 26 (15–40 ng/mL p < 0.001; L-FABP1: 30 (20–46) vs 23 (15–34) ng/mL, p < 0.001) and I-FABP2: 1.3 (0.7–2.3) vs 1 (0.4–2) ng/mL, p = 0.039)] (Supplementary Figure 2).
