Short-term exposure to outdoor nitrogen dioxide and respiratory mortality, with high-risk populations: a nationwide time-stratified case-crossover study.

ABSTRACT: Numerous existing studies reported the negative impacts of outdoor nitrogen dioxide (NO₂) on respiratory mortality. However, the evidence of related high-risk populations was considerably limited, especially associated with ages, causes of death, and district-level characteristics. In addition, most earlier studies were based on monitored areas, thus previous risk estimates of NO₂ could be biased to provide nationwide risk estimates and high-risk populations. Therefore, this study performed a nationwide time-stratified case-crossover study to evaluate the association between short-term ambient NO₂ and respiratory mortality in South Korea (2015-2019). A machine learning-ensemble daily NO₂ prediction model was used to cover unmonitored areas. To ex
