NOTE: In models 1 and 2, the four equations were simultaneously estimated, controlling for population density. In model 1, deprivation entered as categorical variable; low deprivation is referent group. In model 2, vehicle ownership entered as categorical variable; high vehicle ownership is referent group. In both models, population density entered as continuous. Results are reported as multivariate-adjusted b (SE). Statistically significant variables are indicated as: *<0.05 †<0.01 ‡<0.001 |
