Reason for non-thrombolysis. Multivariate analysis of reasons for non-thrombolysis divided by onset-to-admission delay (≤180 min vs >180 min)

Patients (n=2019)	≤180 min (n=659)	>180 min (n=1360)	OR	p Value	95% CI
Too mild stroke	323 (49%)	567 (42%)	3.35*	0.000	1.82 to 6.18
Age >80 years	112 (17%)	164 (12%)	2.98*	0.007	1.36 to 6.56
Other bleeding reasons	15 (2%)	9 (1%)	10.12*	0.026	1.33 to 77.23
Recent stroke (clinically or radiologically) <3 months	36 (6%)	13 (1%)	4.50	0.071	0.88 to 23.01
Other reasons	16 (2%)	8 (1%)	13.77*	0.033	1.23 to 153.68
Microangiopathic stroke mechanism	75 (11%)	233 (17%)	0.28*	0.010	0.11 to 0.74
Other determined or rare stroke mechanism	54 (8%)	32 (2%)	3.48	0.096	0.80 to 15.08
Atrial fibrillation	179 (27%)	287 (21%)	1.94*	0.034	1.05 to 3.58
Mechanical or biological heart valves	23 (4%)	40 (3%)	3.62*	0.049	1.01 to 13.01

OR >1 means more likely ≤180 min and <1 means more likely >180 min.
