Changes in anaphylatoxin (C3a, C4a and C5a) concentrations during treatment with antivenom.

<p>Lowess curve (thick dash-dot line). Upper limit (99^th centile healthy control values from our laboratory) (thin dashed line). There were no significant differences between pre-antivenom concentrations and peak concentrations during the first four hours post-antivenom for C3a, C4a or C5a (p>0.13 for all comparisons, Wilcoxon Signed Rank Test).
