Logistic regression demonstrating the association between referral for immediate care and the number of FAST symptoms mentioned in the simulated calla
| FAST symptoms, n | Odds ratio | 95% CI | P-value |
|---|---|---|---|
| 3 | 1.00 | – | – |
| 2 | 0.35 | 0.15 to 0.83 | 0.017 |
| 1 | 0.30 | 0.13 to 0.72 | 0.007 |
| 0 | 0.03 | 0.01 to 0.08 | <0.001 |
FAST = Face Arm Speech Time test.
