Figure 1 legends:
A . Example map. A typical landscape in Southern Estonia with
different types of green area indicated by different colours; pixel size
is 100x100 m.
B . Sum of model weights for models relating atopic
sensitization with combinations of green area types at different spatial
scales. Fifteen models were constructed at each scale combining green
area types in various ways. Models at the scale of 8 km produced highest
weights.
C . The importance of different green area types at various
spatial scales in models explaining atopic sensitization. Importance was
calculated as the summed Akaike weight from models at a particular
spatial scale where the green area type was included. 95% bootstrap
confidence intervals are shown around mean importance.
D . Predicted probabilities with confidence intervals showing
the likelihood that a child from a home surrounded by a certain amount
of biodiverse nature will be classified to a particular atopic
sensitization group. Ordinal regression model linked three groups of
subjects based on atopic sensitization to the summed area of forests,
grasslands and wetlands within a radius of 8 km of the subject home
location (presented here as the proportion of the circle for better
readability; the model used log-transformed values).
Table 1. Summary of best models from each spatial scale where
atopic sensitization was linked to the areas of green habitat types.
Each row represents a spatial scale from 1 to 10 km. The overall best
model is in bold (8 km radius)
