Description of intervention(s) / exposure
Arm 1
Endovascular Clot Retrieval (ECR)
ECR will be administered to eligible patients who have a stroke due to large vessel occlusion within 24 hours of stroke onset, per standard care, in a public hospital setting.

Arm 2
Intravenous Tissue Plasminogen Activator (t-PA)
t-PA will be administered to eligible patients who have a stroke at the standard dose of 0.9mg per kilogram within four and half hours of stroke onset, per standard care, in a public hospital setting.

As this is a non-randomised trial, participants are assigned to arm 1 or arm 2 based on the treatment they receive from their medical team.

For this study, participants are being assessed 3-months post-stroke.

Retrospective data being collected relates to information about stroke severity and stroke location.

Statistical methods / analysis
We are aiming for a total sample size of 90 participants with 30 participants in each of the three treatment conditions. For cross-sectional analysis of the treatment conditions at 3 months, a MANCOVA will be performed including all cognitive, emotional, and functional outcome measures, with likely covariates including premorbid cognitive functioning and stroke severity. This will be followed by assessment of univariate findings with appropriate Holm’s adjustment to the alpha level to control for Type 1 error.
