Associations with door to PCI time (linear mixed model).

Time (min)	Estimate (95%CI)	p-value
Dispatch time (n = 365) (dispatch - call received)	−0.53 (−2.64 to 1.56)	0.63
Response time (n = 365) (on scene - dispatch)	0.37 (−0.22 to 0.93)	0.20
Time to first ECG (n = 361) (12-lead ECG - at patient)	0.41 (0.01 to 0.82)	0.046
Activation time (n = 327) (cath lab activation - 12-lead ECG)	0.90 (0.82 to 0.98)	<0.001
Scene time (n = 365) (depart scene - on scene)	1.15 (0.55 to 1.75)	<0.001
Transport time (n=365) (at destination - depart scene)	−0.28 (−0.63 to 0.13)	0.13
Total EMS time (n = 365) (at destination - on scene)	0.09 (−0.18 to 0.39)	0.52
