Non‐linear short‐term effects of airborne pollen levels with allergenic capacity on asthma emergency room admissions in Madrid, Spain

Abstract

Pollens with allergenic capacity in Madrid are positively associated with asthma-related hospital emergencies. These associations remain stable when simultaneous adjustment is made for the four types of pollen and for air pollutants and meteorological variables. In terms of non-linear effects, Poaceae register the strongest association with asthma emergency room admissions.
