Logistic model significant predictors of stroke time intervals exceeding emergency medical services guidelines

Predictors	Coefficient	p-value	95 % Confidence Interval
Outcome: Total Time > 60 Min
EMS 1	0.277	<0.0001	0.205, 0.373
2	Referent	Referent	Referent
Specialty Center (No)	0.710	<0.0174	0.536, 0.942
(Yes)	Referent	Referent	Referent
Outcome: Response Time > 10 Min
EMS 1a	0.885	0.0938	0.767, 1.021
2	Referent	Referent	Referent
Outcome: On-Scene Time > 15 Min
Age (x10 years)	1.147	<0.0001	1.081, 1.217
EMS 1	0.773	<0.0001	0.685, 0.871
2	Referent	Referent	Referent

^aNone of the variables were significant in the logistic model but EMS was forced in the model because of the apriori belief that EMS is a potentially important predictor
