Table 6: Effect of Time to Randomization on Outcome of Treatment Comparison in the 5-Year Followup Study by Bonnefoy et al. (7).

Mortality	Patients Included ≤2 Hours of Symptom Onset		Patients Included >2 Hours of Symptom Onset
	Pre-Hospital Fibrinolysis	Primary PCI	Pre-Hospital Fibrinolysis	Primary PCI
% (n)	5.8% (n=13)	11.1% (n=25)	14.5% (n=27)	14.4% (n=26)
HR (95% CI)	0.50 (0.25 to 0.97), P=0.04		1.02 (0.59 to 1.75), P=0.92
Interaction of treatment strategy with time to randomization HR (95% CI)	1.02 (0.59 to 1.75), P=0.10

HR refers to hazard ratio; CI, confidence interval
