Relationship between land-use types around the home at birth and at 6 years of age and prevalence of atopic sensitization at 6 years of age, for children that moved home between birth and 6 years of age in the LUKAS cohort (n = 97). The prevalence of atopy (log₁₀(IgE) > IgE_th) at 6 years of age was explained by the land-use gradient associated with the home at birth and the home at 6 years of age in a logistic regression model (the two gradients were positively correlated, r = 0.51, P < 0.001). The regression estimate gives the direction and magnitude of the relationship between the land-use gradient (relative increase in forest and agricultural land) and atopy. OR is odds ratio (exp(Estimate))
