Changes in MCT and histamine 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). Normal limit defined by assay (MCT only) (thin dotted line). * p-value for difference between pre-antivenom concentration and peak concentration during the first four hours post-antivenom (Wilcoxon Signed Rank Test).
