			use = <"Använd som stöd till klinisk bedömning av strokerisk i samband med transitorisk ischemisk attack (TIA). Instrumentet baseras på fem parametrar som vardera bidrar till totala summan enligt:

- Ålder: 1p för ≥60 år
- Blodtryck: 1p för systoliskt BT ≥140 och/eller diastoliskt BT ≥90
- Kliniska fynd (TIA): 1p för språkrubbning utan ensidig svaghet, 2p för ensidig svaghet
- Symtomduration (TIA): 1p för 10-59 min, 2p för ≥60 min
- Diabetes: 1p för diagnosticerad diabetes

Total poäng uppgår till maximalt 7p, och resultatet tolkas enligt:

1-3p = låg risk, 2-dagars risk 1,0%, 7-dagars risk 1,2%, 90-dagars risk 3,1%
4-5p = måttlig risk, 2-dagars risk 4,1%, 7-dagars risk 5,9%, 90-dagars risk 9,8%
6-7p = hög risk, 2-dagars risk 8,1%, 7-dagars risk 11,7%, 90-dagars risk 17,8%">
