The aim of the study is to investigate the effect of AR on school performance and examination test grades for children and adolescents diagnosed with AR early in life, as well as analyse their burden of disease and healthcare resource use using real-world data from the exhaustive Danish population registers. This is a retrospective registry analysis that uses Danish registers during 1994 and 2021.~In Denmark, national registers collect data for the entire Danish population from birth to death and have done so for decades. This exhaustive data creates a sound foundation for this study of the impact of school performance caused by AR, as subjects can be traced with high certainty and detail over several years.
The study will assess the the burden of living with allergic rhinitis (AR) and the effect of AR on school performance for children and adolescents in Denmark.
