Compared to the patients in the moderate group, severe patients were more susceptible to hepatic insufficiency, as indicated by the elevation of aspartate aminotransferase (AST) [33.5 (23.75-68) vs. 21 (18-27) U/L, P = 0.004] and lactate dehydrogenase (LDH) [389.5 (241.5-497.5) vs. 197.5 (160.25-229.75) U/L, P = 0.002], and the decreased albumin concentration [35.5 (32.75-38.25) vs. 42 (39-44) g/L, P = 0.003]. Here, ALB is linked to Hepatic failure.
