title: Predictive value of ABCD2 and ABCD3-I scores in TIA and minor stroke in the stroke unit setting.
abstract: OBJECTIVE
  It is not clear whether risk scores for early stroke recurrence after TIA that have been mainly established in outpatient and emergency department settings are valid on the background of highly specialized stroke unit care.
  
  
  METHODS
  ABCD2 and ABCD3-I scores have been prospectively documented in a cohort of patients admitted to Austrian stroke units within 24 hours of symptom onset with TIA or minor stroke (NIH Stroke Scale score <4).
  
  
  RESULTS
  A total of 5,237 TIA and minor stroke patients met inclusion criteria, with 3-month follow-up data available on 2,457. Early and 3-month stroke were observed in 2.4% and 4.2% of the study population. The probability of early stroke during the stroke unit stay (median 2 [interquartile range 1-3] days) steadily increased from 0% to 4.8% and 0% to 16.7% with increasing ABCD2 and ABCD3-I score points, respectively. On 3-month follow-up, stroke risk increased from 0% to 8.0% and 0% to 23.8% with increasing ABCD2 and ABCD3-I score points, respectively. Of the individual score components, age, blood pressure, and diabetes were not related to early or 3-month stroke, whereas clinical presentation (C), symptom duration (D), and cerebral as well as carotid imaging (I) were and accounted for the information provided by the full scores.
  
  
  CONCLUSIONS
  Standard ABCD2 and ABCD3-I scores are useful instruments to estimate the probability of early and 3-month stroke in TIA and minor stroke patients treated at specialized stroke units, with C, D, and I being the most important score components in this setting.
