    Additional information

    Date derived from derivation groups California emergency department (n=1707) and Oxford population based (n=209),Volume 369, Issue 9558, 27 January–2 February 2007, Pages 283–292.

    The study populations included various clinical settings in two dissimilar populations, from the Kaiser-Permanente Medical Care Plan (KPMCP) in Northern California, USA, and from Oxfordshire, UK, studied over a range of periods. Each study evaluated risk of stroke after an initial TIA in a clearly defined group that was representative of the local population and used rigorous methods to assure complete ascertainment of events during follow-up.

    Result interpretation


    Note:
    The ABCD2 score was developed in the outpatient (non-emergency department) setting. Its purpose is to help physicians risk stratify patients presenting with a TIA for how likely they are to suffer a subsequent stroke.
