Figure 2.

Correlation between the age of the patient and the choroidal thickness at different sites. Circle radii are proportional to the estimated correlation. Numbers represent the beta coefficients of the multivariate model for age at different sites (calculated from the interaction term in the model). Asterisks indicate in which sites the correlation between choroidal thickness and age is significantly different from the one found in the subfoveal region (chosen as the reference level in the model).
