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 specicif 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.

VISTA-Cognition

The VISTA Collaboration is expanding once again, with the addition of an archive of data specific to trials for cognitive impairments after stroke (VISTA-Cognition). The aim is to be inclusive; information on the eligibility criteria and data contribution procedure will be available by mid-June 2015.

To date we have received 6 datasets, totalling 1,394 individual patients' data. We encourage further contributions of datasets to VISTA-Cognition and will make more informaiton available on the variables that cane be used in analyses.
