mRS, modified Rankin scale score; OR, odds ratio.
These models were adjusted for baseline NIHSS score and history of ischemic stroke.
Univariate logistic regression analysis was performed due to the failure of fitting a multivariate model adjusted for baseline NIHSS score and history of ischemic stroke.
There were two cases (3.9%) of parenchymal hemorrhage type 2 according to the criteria of ECASS II in the alteplase group, one of the two cases had symptomatic intracranial hemorrhage in the infarcted region and left severe disability.
