Correlations between sPLA₂ activity and complement components. sPLA₂ activity in patients with different functional activity of C1-INH. (A) Correlation between sPLA₂ and C1-INH activity was assessed by Spearman’s correlation analysis and reported as coefficient of correlation (r). (B) Patients were divided in two groups: C1-INH type I patients with less than 25 or 25–50% of normal C1-INH protein values. (C) Patients were divided in two groups: C1-INH-HAE patients with less than 25 or 25–50% of normal C4 values. Activity of sPLA₂ (B,C) is shown.
