Stroke Research Intelligence
Stroke protocols frequently include time windows relative to symptom onset. Time-based criteria are the ones most likely to be unresolvable from stored records, and the interface should say so rather than assume.
Screening support only. ClinQSphereX provides research and recruitment workflow support. It does not independently determine clinical eligibility, diagnosis, treatment or enrolment. Candidates are shown as potentially eligible and require researcher review.
Conditions in scope
- Ischemic stroke
- Hemorrhagic stroke
- Transient ischemic attack
- Stroke rehabilitation
Research variables
Synthetic data- Age
- Previous stroke history
- Blood pressure
- Time since documented event
- Relevant comorbidities
- Anticoagulant medication history
Variables are only used when they exist in the underlying dataset. Demonstration records are synthetic and are not real patient data.
Why screening is hard here
Onset timing is often absent from structured data — those criteria remain UNKNOWN.
Clinical trial discovery
Live dataRecords are retrieved from the public ClinicalTrials.gov registry when you search. Nothing on this panel is a determination about any individual.
Structured eligibility screening
Synthetic dataProtocol text becomes one row per criterion. Each row records the expected value and the observed value, and resolves to PASS, FAIL or UNKNOWN. Missing information stays UNKNOWN — it is never converted into a pass.
| Criterion | Expected | Illustrative outcome |
|---|---|---|
| Age | ≥ 18 years | PASS |
| Documented cerebrovascular event | Present | FAIL |
| Time since onset | Within protocol window | UNKNOWN |
| Anticoagulant therapy | Protocol dependent | PASS |
| Blood pressure | < 185/110 mmHg | FAIL |

Limitations for this area
- Onset timing is often absent from structured data — those criteria remain UNKNOWN.
- Demonstration records are synthetic; no real patient data is used on this site.
- Registry records are shown as published by ClinicalTrials.gov and are not verified against any individual.
- Model output is a prediction, not a diagnosis, and never changes a participant's status on its own.
