Asthma prevalence among children within each of the four different IgE categories by age-adjusted/-standardized (mean 0, standard deviation 1) IgE Z scores of < −0.8, −0.8 to < 0, 0 to < 0.6, and ≥ 0.6. There was a statistically significant increasing trend of asthma prevalence with each quartile (Cochran-Armitage trend test p = 0.001; Fisher's exact p = 0.002).
