  1. Numbers represent regression coefficients (95% CI).
  2. *Only individuals that have reported some walking are included and values are log-transformed.
  3. a paths: Associations between walkability parameters and vehicle ownership.
  4. b paths: Associations between vehicle ownership and walking for active transportation (log-transformed min/week).
  5. c paths: Associations between walkability parameters and walking for active transportation (log-transformed min/week).
  6. c’ paths: c paths adjusted for vehicle ownership.
  7. ab paths are not based on the walkability parameters.
  8. bAdjusted for age, gender, income and marital status.
  9. n/a: Not applicable (as no significant association was found between the walkability parameter and the physical activity outcome).
