IGHE and asthma: We observed that among asthma patients with different phenotypes, Clusters D (value of 25th, 50th, and 75th percentiles: 41.3, 138.5, and 298.0 U/mL) and F (36.8, 103.0, and 301.0 U/mL) exhibited relatively higher total IgE levels, indicating higher DEHP exposure risks, surpassed only by Cluster E of current smokers and Cluster C of ex-smokers.
