ABCD² Score as a Predictor of Three-Year Stroke Risk

This retrospective cohort study using the National Patient Registry in Denmark analyzed a three-year follow-up period following a transient ischemic attack, looking at the rate of recurrent stroke and mortality. The patients were divided into low risk (ABCD² score 0-3) and high risk (ABCD2 score ≥ 4). The stroke rate was 6% in the high-risk group and 4% in the low-risk group.
