Sponsored by Chiayi Christian Hospital · Observational
This study aims to validate a machine learning model that stratifies the risk of stroke in patients who present to the emergency department with dizziness or vertigo.
This is a cross-sectional, hospital-based study, with no randomization procedure. Over a 21-month period, approximately 600 subjects will be enrolled. The study will assess the risk of stroke in each patient using a machine-learning model. To detect ischemic or hemorrhagic stroke, each patient will undergo a non-contrast brain magnetic resonance imaging study. The predictive performance of the machine-learning model will be evaluated in terms of accuracy, precision, recall, F1 score, and area under the receiver operating characteristics curve.
226 studies on the registry are indexed under Dizziness; 56 are open to participants now.
This study's planned enrollment of 600 is above the median of 126 across 44 observational studies indexed under Dizziness.
