Statistical analysis
The agreement scale was dichotomized as “agree-to-strongly agree”
(agree and strongly agree) and “not agree-to-strongly agree” (strongly
disagree, disagree and undecided). Similarly, the interest scale was
dichotomized as “very-to-extremely interested” (very interested and
extremely interested) and “not very-to-extremely interested” (not
interested, slightly interested and moderately interested).
A binomial logistic regression analysis was performed to predict the
likelihood of being very to extremely interested or not in app
development described above stratified by age, gender, educational
level, region, living area, economy according to the World Bank data,
urticaria type and years with diagnosis. All data were analyzed using
SPSS version 24.0 software (SPSS Inc., Chicago, IL, USA).
