Variables
The study analysed data regarding atopic history, previous reactions,
co-factors, symptoms, severity and timing of reaction, emergency
treatment and long-term management. Variables were reported as a
fraction of valid answer options, with multiple selections possible for
some questions. All variables except for age at reaction, gender and
symptoms were allowed to remain missing by item, therefore the
denominator used to calculate percentages did slightly vary from the
total for some variables. Specific areas covered and the online version
