Assessing Repeatability and Reproducibility of Anterior Active Rhinomanometry (AAR) in Children

2020

AbstractBackgroundRepeatability and reproducibility are essential for clinicians for several purposes. Although discouraged, use of the Coefficient of Variation (CV) for assessing repeatability and reproducibility, rather than the Intraclass Correlation Coefficient (ICC), is still widespread. The aim of the present study was to highlight how using inappropriate indices may lead to misleading results, and this is done by simulation study and using real data on Anterior Active Rhinomanometry (AAR) in both healthy children and ones with rhinitis.MethodsA simulation study was carried out to highlight how using inappropriate indices could be misleading. Then a comparison was made between CV and …
