  1. a paths: Associations between walkability parameters and vehicle ownership.
  2. b paths: Associations between vehicle ownership and walking for active transportation (dichotomous, yes/no).
  3. c paths: Associations between walkability parameters and walking for active transportation (dichotomous, yes/no).
  4. c’ paths: c paths adjusted for vehicle ownership.
  5. ab paths are not based on the walkability parameters.
  6. bAdjusted for age, gender, income and marital status.
  7. n/a: Not applicable (as no significant association was found between the walkability parameter and the physical activity outcome).
