Other comments | Another questionnaire, Rhinitis Quality of Life Questionnaire has been published (Juniper EF, Guyatt GH, Andersson B, Ferrie PJ. Comparison of powder and aerosolized budesonide in perennial rhinitis: validation of rhinitis quality of life questionnaire. Annals Allergy 1993; 70: 225-230); however, because the majority of rhinits patients have eye symptoms it is recomenced that Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), which is summarized here, is to be used (click here). |
