Table 4: Outcomes in Canadian patients presenting with acute ischemic stroke who received thrombolysis during the study period

	Proportion of patients, %*
Outcome	Comprehensive stroke centre n = 297 N, weighted = 1363.8 (66.5%)	Primary stroke centre n = 162 N, weighted = 569.4 (27.8%)	Other n = 21 N, weighted = 116.3 (5.7%)	All hospitals n = 480 N, weighted = 2049.5	p value†
In-hospital death at 7 d	7.2	8.3	5.2	7.4	0.5
In-hospital death at 30 d	13.3	15.1	10.8	13.6	0.4
Hemorrhagic transformation	8.0	7.2	—	7.3	0.006
Length of stay, d, mean ± SE	15.7 ± 1.3	16.7 ± 4.7	15.7 ± 2.5	16 ± 1.6	< 1.0

Note: SE = standard error. *Unless otherwise stated †Test of proportions among 3 groups; length of stay was assessed by analysis of variance. The only difference between groups was seen on hemorrhagic transformation because no hemorrhages occurred in one group with a very small sample.
