Abstract

Prognostic models are used to predict outcome in stroke patients and to stratify treatment groups in clinical trials. No one has previously attempted to use such models in stroke recovery studies in animals. We have now shown the predictive value of assigning stroke severity ratings, based on behaviours displayed in conscious rats during infusion of endothelin-1 to constrict the middle cerebral artery, on neurological and histological outcomes. The validity of prior stratification of treatment groups according to stroke ratings was tested by assessment of the protective potential of synthetic flavonol, 3',4'-dihydroxyflavonol (DiOHF). Neurological deficits and performance on the sticky label..
