MeasureTime frameDescription
Total Nasal Symptom Score (TNSS)56 daysScore 0 - asymptomatic; Score 1 - mild symptoms, easily tolerated; Score 2 - moderate symptoms, annoying but tolerable; Score 3 - Severe symptoms, intolerable, affecting daily life and sleep. Add them together to get the total score
Visual Analogue Scale (VAS)56 days0 means no such symptoms; 10 means that this symptom is the most severe. Add them together to get the total score
Rhinoconjunctivitis-related quality of life questionnaire (RQLQ)56 days0 points: no trouble; 1 point: little to no distress; 2 points: occasional distress; Score 3: Moderate degree of distress; 4: Somewhat bothered, 5: Very bothered; Score 6: Extremely distressed
