Multiple linear regression analysis for independent predictors of the door-to-reperfusion time in phases 3 and 4
| Variable | Unstandardized coefficient (95% CI) | SE | Standardized coefficient | P value |
| EMS pre-notification | −98.7 (−136.1 to −61.3) | 18.9 | −0.409 | <0.001 |
| Onset-to-door time (per 60 min increment) | 4.7 (1.9 to 7.6) | 1.4 | 0.256 | 0.001 |
| Cardioembolism | −34.2 (−64.3 to −4.1) | 15.2 | −0.175 | 0.026 |
The variables identified by the backward selection procedure are listed.
