Correlation of serum LL37 and IFNα levels with serological parameters. (A) The serum LL37 levels were positively correlated with the interferon alpha (IFNα) levels (R = 0.577, P = 0.000). (B), (C) Both the serum LL37 (R = 0.437, P = 0.000) and IFNα (R = 0.337, P = 0.004) levels showed a positive correlation with the serum creatinine levels, (D), (E) but not with the complement C3 levels (LL37: R = 0.020, P = 0.871; IFNα: R = -0.12, P = 0.922).
