Relationship between the four metrics of severity: Pearson correlation coefficients above the diagonal; numbers of participants below the diagonal
| Did not continue by bike | Transported to hospital by ambulance | Admitted to hospital | CTAS* | |
|---|---|---|---|---|
| Did not continue by bike (n=528) | – | 0.40 | 0.17 | −0.29 |
| Transported to hospital by ambulance (n=251) | 249 | – | 0.24 | −0.39 |
| Admitted to hospital (n=60) | 60 | 45 | – | −0.20 |
| CTAS=1 or 2 (n=75) | 74 | 62 | 17 | – |
*Correlations with CTAS were negative because the scale was in the opposite direction, with 1=most urgent and 5=least urgent. All other metrics were assigned 1=more versus 0=less severe.
