Geometric mean isotype responses to SWA, SmTAL1, SEA, SmTAL2, AHW, and Na-ASP-2 over age before (solid line) and 8 weeks after (dashed line) treatment. Detection thresholds were added to values before calculating GMs to remove nonpositive values. IgE levels are expressed in ng/ml, and IgG1 and IgG4 levels are expressed in μg/ml.
