Figure 4: IL-27 levels were positively correlated with the expression of immunoglobulins. (a) IgG levels were found to be positively correlated with IL-27 levels; and a positive correlation trend was found between IgM levels and IL-27 levels in HBV-ACLF patients. (b) Positive correlations were found between IL-27 levels and serum immunoglobulin levels (IgG, IgA, and IgM) in HBV-infected patients. Solid line: linear growth trend; : correlation coefficient. values are shown.
