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. 

Using this resource, specific questions can be answered concerning the natural history of subgroups, the optimal selection of patients for future trials, choice of outcome measures, the influence of country, concomitant disease and other factors on recovery.
