Outcomes in Patients With Acute Ischemic Stroke Comparing ET vs IV tPA

Outcome at 90 d	ET vs IV tPA
Outcome at 90 d	ET (n/N)	Control (n/N)	RR (95% CI)	I² statistic (%)
mRS score ≤1	194/685	135/478	1.02 (0.84–1.23)	1
mRS score ≤2	275/685	189/478	1.02 (0.84–1.24)	21
mRS score ≤3	397/685	270/478	1.03 (0.93–1.14)	0
Mortality	127/707	84/490	0.98 (0.76–1.25)	0
sICH	42/707	30/490	0.99 (0.62–1.58)	0

ET = endovascular therapy; IV = intravenous; mRS = modified Rankin Scale; n/N = No. of patients with stroke/total No. of patients with outcome; RR = risk ratio; sICH = symptomatic intracranial hemorrhage; tPA = tissue plasminogen activator.
