(a) Comparison of levels of Malassezia‐specific serum IgE, stratified by the presence of dupilumab‐associated head and neck dermatitis (DAHND) or no DAHND. (b)

Logistic regression analysis of factors associated with DAHND not including (model 1) and including (model 2) a priori covariates. (c) Receiver operating characteristic (ROC) curve and area under the curve (AUC) analysis of Malassezia‐specific serum IgE. OR, odds ratio; CI, confidence interval; EASI, Eczema Area and Severity Index. Variables and their P‐values shown in bold were considered statistically significant (P < 0·05).
