Allocation and randomization
Randomization is performed using a randomization list in which, based on 165 randomly generated numbers sorted by size, each of the available options is assigned according to the planned sample size (WLC = 43, APP = 61, TG-APP = 61). The list is then sorted by sequential number. A study coordinator who is not involved in the diagnosis or treatment process will enter the subjects into the randomization list according to the order of inclusion. The result is communicated to the patients via email and remains hidden from the clinical evaluators. The email to the participant contains the result and, if the person belongs to one of the two intervention groups, all the necessary information to use the app.
