Box plot according to monophasic anaphylaxis and biphasic anaphylaxis; horizontal bars are median, box edges are interquartile range and whiskers are range.
Monophasic (µg/L): median (range) = 4.2 (1–19.5); SD = 3.1 (n=224)
Biphasic (µg/L): median (range) = 6.1 (1.7–22.2); SD = 5.4 (n=13)
*p = 0.009 (after unpaired signed-rank Wilcoxon test)
