International Stroke Trial database (version 2)

The International Stroke Trial (IST) was one of the biggest randomised trials in acute stroke. Methods: Available data on variables assessed at randomisation, at the early outcome point (14-days after randomisation or prior discharge) and at 6-months were extracted and made publically available. Results and Conclusions: The IST provides an excellent source of primary data easy-to-use for sample size calculations and preliminary analysis necessary for planning a good quality trial. # Associated publications # * The erratum paper explains the difference between this version ie version 2, and the previous version: Sandercock, P.A.G., Niewada, M., Członkowska, A. et al.
