The<unk>  is a clinical prediction rule used to determine the risk for stroke in the days following a transient ischemic attack (TIA, a condition in which temporary brain dysfunction results from oxygen shortage in the brain). Its usefulness was questioned in a 2015 review as it was not found to separate those who are at low from those who are at high risk of future problems. A high score correctly predicted 87% of the people who did have a stroke in the following 7 days but also many people who did not have problems. The<unk>  is based on five parameters (age, blood pressure, clinical features, duration of TIA, and presence of diabetes); scores for each item are added together to produce an overall result ranging between zero and seven. People found to have a high score are often sent to a specialist sooner. Other clinical risk factors, such as atrial fibrillation and anticoagulation treatment, as well as ongoing or recurrent TIA, are also relevant. The<unk>  was proposed in 2007 as a modified version of the<unk>  of 2005 (the<unk>  did not consider the presence of diabetes). In the largest study based on emergency department testing of the<unk>  in an acute setting, the score performed poorly in both high-risk and low-risk patients. The study found the score to be 31.6% sensitive in high-risk patients (score >5) and only 12.5% specific in low-risk patients (score ≤2).
