  1. The table shows the number of ED contacts in each outcome. Presented by triage category vertically and the triage system horizontally. Percentage (%) is the share of all patients allocated to the triage system. Length of stay is presented as median (hours) and Interquartile Range. The result of corresponding statistical analyses is presented in the right column
