Age and sensitization profiles
We observed an increase in the numbers and levels of c-sIgE sensitization with age, both among non-severe and severe patients (Fig 2). In particular, there was an increase in the number of positive biological sources for airborne (RR 1.14 [1.08 – 1.20], p<0.0001) and cross-reactive components (RR 1.18 [1.07 – 1.30] per one-year increase in age, p=0.00098), but not for food biological sources (Sup Fig 2, Sup Table 3).
