Research Status and Thinking of Minimal Clinically Important Difference in Patient-reported Outcome Assessment Tool for Allergic Rhinitis

As the patient-reported outcome (PRO) assessment tool has been increasingly used in the clinical efficacy evaluation of patients with allergic rhinitis (AR) , the judgment and interpretation of changes in measurement results of assessment tools have become increasingly important. For the judgment of clinical research results, not only the statistical differences, but also the minimum clinically important difference (MCID) must be paid attention to. This paper systematically sorts out the MCID of the AR-PRO assessment tool, in order to provide a reference for AR-related clinical diagnosis and treatment decision-making and the objectification of the PRO assessment tool.
