Table 4.
Proportions (%) of patients with each variable among the patients with and without each secondary outcome. I.e. 7.1% of patients requiring PICU admission and 1.0% of patients not requiring PICU admission had a previous EMS contact. Comparisons between the proportions with and without were made using Fisher’s test
