IL-6 correlates with AST and is increased in patients with impaired liver function. (A) IL-6 and AST levels correlate in all hospitalized patients. (B) IL-6 levels correlate with AST concentration in non ICU and ICU patients. Displayed are IL-6 concentrations in patients with normal AST and elevated AST in (C) non ICU and (D) ICU patients. Data are shown as mean ± SEM, n: (C-D). *p<0.05; **p<0.01; ***p<0.001 according to Spearman correlation or Student's t-test. AST, aspartate aminotransferase; ICU, intensive care unit; IL-6, interleukin 6.
