Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Objectives: To compare clinician judgment with the use of a validated stroke risk score (iScore) and patients' outcomes.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
All participants are active practicing physicians caring for patients with acute stroke. Conditions were standardized to mimic clinical practice.
Main outcomes of interest included 30-day mortality and death or disability at discharge.
Secondary outcome: death or institutionalization at discharge

Randomized clinical scenarios
Clinicians are randomized to a sequence of 5 clinical scenarios
Clinical scenarios
Clinicians will be randomized to a sequence of 5 clinical scenarios with a variable range of expected outcome \[i.e. from low (\<10%) to high (\>50%) expected risk death at 30 days\].
