Key findings

What ClinicalTrials.gov does not surface for Stroke on its own pages , computed from the registry mirror as of 2026-07-11. Each line carries its own denominator so it can be quoted as it stands.

  1. Stroke is recruiting above its size-band peers.

    218 of 456 indexed trials (47.8%) are open to enrollment, against a 37.2% average across 135 conditions with 100+ trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of Stroke trials is spread across many organizations.

    VA Office of Research and Development accounts for 27 of 456 trials (5.9%). 181 distinct sponsors appear on at least one study for this condition label.

  3. Most Stroke trials plan to enrol fewer than 100 people.

    Median target enrolment is 54 among the 455 trials that report a genuine target (sentinel values excluded). 309 of those (67.9%) plan for fewer than 100 participants.

  4. Stroke research is mostly interventional.

    385 interventional and 71 observational studies make up this index (84.4% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
