a paths: Associations between walkability parameters and vehicle ownership.
b paths: Associations between vehicle ownership and MVPA (minutes/day).
c paths: Associations between walkability parameters and MVPA (minutes/day).
c’ paths: c paths adjusted for vehicle ownership.
ab paths are not based on the walkability parameters.
bAdjusted for age, gender, income and marital status.
n/a: Not applicable (as no significant association was found between the walkability parameter and the physical activity outcome).
