Table 3 Persistence of AD and appearance of RC and/or asthma in relation to hen's egg sensitization assessed through sIgE (levels of IgE > 0.35 KU/L, between 0.35 and 2 KU/L and > 2 KU/L), and through SPT at first observation.

From: Does improvement management of atopic dermatitis influence the appearance of respiratory allergic diseases? A follow-up study
