Comparison of Stroke Prediction Accuracy of ABCD2 and ABCD3-I in Patients with Transient Ischemic Attack: A Meta-Analysis

ABCD3-I scores had a better sensitivity but poorer specificity than ABCD2 scores. However, in community-based referring settings, it is more suitable to use ABCD2 at initial triage and deciding on urgency of specialist assessment. The prognostic utility of each of the components of the scores should be carefully considered rather than dichotomized scores during clinical triage.
