Early Warning System for Allergic Rhinitis in the MASK-air® App

The primary objective consists in the comparison of the combined symptom medication score values between (i) patients randomised to the early warning system personalised forecasting messages, and (ii) patients randomised to generic messages already delivered by MASK-air®. The combined symptom medication score has recently been developed in a data-driven way and validated (https://eaaci.org/images/CSMS.pdf); it assesses allergic rhinitis control taking into account both reported symptoms and medication use. As secondary objectives, visual analogue scales on allergic rhinitis symptoms (VAS global, nasal, eye, asthma), and medication use will also be separately compared.
