Knowledge mapping of covid-19 and asthma/allergic rhinitis: a visual and bibliometric analysis
The COVID-19 pandemic has significantly impacted global health, with particular concerns for patients with pre-existing respiratory conditions such as asthma and allergic rhinitis (AR). This study conducts a bibliometric and visual analysis to map the knowledge structure, research trends, and key themes in the intersection of COVID-19, asthma, and AR. Using data from Web of Science and Scopus, we analyzed publication trends, authorship networks, keyword co-occurrence, and thematic evolution.
