ColdU Demographics Compared to CSU (Table 1)
We extracted data on a total of 103 pediatric CSU patients from the
Netchiporouk et al. study10. Median age of disease
onset was 5.0 years (IQR: 2.0, 10.0) and approximately half (48.5%) of
CSU patients were female. There was a significantly higher proportion of
coldU patients with comorbid asthma (P=0.030), atopic dermatitis
(P=0.012), and elevated IgE levels (P=0.010) compared to CSU patients.
Mean age of onset was significantly higher in coldU patients
(P<10-3). No significant differences were
identified in other demographics, comorbidities, or laboratory values.
