Impact of age, sex, and urban environment on allergen-specific IgE profiles to grass pollen components: a cross-sectional study in Northern Italy

This cross-sectional study highlights that demographic and environmental factors - particularly sex, age, and urban living - can influence IgE sensitization to grass pollen components. These findings emphasize the relevance of molecular diagnostics in understanding allergy epidemiology and support the hypothesis that environmental exposure, including air pollution, may affect sensitization profiles.
