The counts of eosinophils did not correlate with sIgE presence (p = 0.74), clinical symptoms of allergy (Tables S3 and S5; p = 0.62), skin eczema (p = 0.85), recurrent respiratory tract infections (p = 0.29), or total IgE level (p = 0.66). This evidence concerns the gene IGHE and Respiratory tract infection.
