ORs (95% confidence limits) for associations between various characteristics and hospitalisation rates for injuries to any body region and injuries to the brain, head, scalp, skull or face, for all injury causes and traffic-related injury causes

  • Bold indicates statistical significance.

  • *Forty-four rates available for modelling: 11 jurisdictions × 2 age groups × 2 sexes; model for injuries to any body region includes random effect for jurisdiction.

  • †Twenty-two rates available for modelling: 11 jurisdictions × 2 age groups.

  • ‡Coefficient represents the multiplicative reduction in the traffic-related hospitalisation rate for each 1% increase in mode share. Note that this relationship was observed within the range of low mode shares (0.23–2.05%) of the jurisdictions in this study.
