</a>
The International Stroke Trial (IST) was one the biggest randomised trials ever conducted in acute stroke.
Patients were assessed at randomisation, at the early outcome point (14-days after randomisation or prior discharge) and at 6-months.
There is an incredible lack of transparency in clinical trial results today. A team at the University of Edinburgh has been working
to change that, and has made the individual patient-level data available for public use,
to facilitate the planning of future trials and to permit additional secondary analyses.
