The Virtual International Stroke Trials Archive (VISTA) is a collaborative venture that collates data from completed clinical trials and provides access to anonymised data for novel exploratory analyses to inform clinical trial design.
Across the entire archive, data are available on more than 82,000 individual patients and are stored anonymously.
Using this resource, specific questions can be answered concerning:
- the natural history of specific population subgroups
- the optimal selection of patients for future trials,
- choice of outcome measures for future trials,
- the influence of country, concomitant disease and other factors on recovery.
