a
Odds ratios (OR) and 95% confidence interval (CI) were estimated using logistic mixed models taking into account the hierarchical structure (students nested within schools). Fixed effects were gender, age, and county, urbanization, tax income and educational level of the place of residence.
b
P of interaction between individual SES and spatial accessibility.
