BACKGROUND AND PURPOSE There is little agreement on how to assess outcome in acute stroke trials. Cutoff scores for the Barthel Index (BI) and modified Rankin Scale (mRS) are frequently arbitrarily chosen to dichotomize favorable and unfavorable outcome. We investigated sensitivity and specificity of BI cutoff scores in relation to the mRS to obtain the optimal corresponding BI and mRS scores. METHODS BI and mRS scores were collected from 1034 ischemic stroke patients. Sensitivity and… CONTINUE READING
