Key result
The ABCD score showed a non-significant trend for predicting high-risk causes of cerebral ischemia (P for trend=0.11), with patients scoring <4 still having a substantial probability of high risk.
Why the study?
Does the ABCD score accurately identify low-risk patients among those hospitalized with acute transient ischemic attack?
Cohort (n=117)
Does the ABCD score accurately identify low-risk patients among those hospitalized with acute transient ischemic attack?
p-value: p=0.11
Patients with an ABCD score <4 still have a substantial probability of having a high-risk cause of cerebral ischemia or radiographic evidence of acute infarction, challenging its utility for identifying minimal-risk TIA patients.

Questions ABCD score utility for identifying low-risk TIA patients; challenges its role and leaves open prospective validation of alternatives.
Cucchiara et al. (2006) conducted a cohort in Acute Transient Ischemic Attack (n=117). ABCD Score was evaluated on High-risk classification (stroke or death within 90 days, ≥50% stenosis, or cardioembolic source) (p=0.11). The ABCD score showed a non-significant trend for predicting high-risk causes of cerebral ischemia (P for trend=0.11), with patients scoring <4 still having a substantial probability of high risk.
