Figure 1. Associations between greenness, trees and allergenic trees in 500 m buffers around birth residential addresses with allergic outcomes up to 15 years, estimated by GEE models and stratified by NO2 levels. Circles represent the low tertile of NO2 while triangles represent the high tertile. An asterisk identifies a significant interaction term between the exposure variable and the continuous NO2 variables.
All models were adjusted for age, sex, season of birth, parental atopy and parental education.
Allerg. – allergenic; CI – confidence interval; def. – definition; OR – odds ratio; NDVI – Normalized Difference Vegetation Index; NO2 – nitrogen dioxide.
