In this large prospective multi-center study of patients diagnosed with TIA, the ABCD2 score was poorly predictive of stroke at 7 or 90 days, regardless of cut-off for “high risk” used. At a high risk cut-off of >2, the sensitivity and specificity of stroke at 7 days was 95% and 13% respectively. At a high risk cut-off of 5, the sensitivity at 7 and 90 days was only about 30%. In this large prospective cohort, the ABCD2 score performed poorly at predicting stroke risk, regardless of “high risk” definition (abstract)
