Methods
The scope, methodology, conduct, and other results of the CURICT study have been previously reported.1,2 Briefly, a 23-item questionnaire2 was completed by 1,841 CU patients from 17 UCAREs across 17 countries. Here, we analyzed patient responses to the CURICT questions on the use of apps for urticaria-related purposes. As previously published, the majority of respondents had chronic spontaneous urticaria (CSU; 63%; 18% chronic inducible urticaria [CIndu]; 19% with both), were female (70%) and lived in urban areas (75%) with a mean age of 41 years, and ~4 years of disease duration.1,2
