    5-6 years after active or placebo ILIT

  • Combined symptoms and medciations score

    Pollen season 5-7 years after active or placebo ILIT

  • Rhinoconjunctivitis quality of life questionnaire

    Pollen season 5-7 years after active or placebo ILIT

  • Sinonasal outcome test quality of life questionnaire

    Pollen season 5-7 years after active or placebo ILIT

  • Allergen specific IgE

    5-6 years after active or placebo ILIT

  • +2 more secondary outcomes
