An integer-based score to predict functional outcome in acute ischemic stroke: The ASTRAL score

Ntaios et al.1 reported on the ASTRAL score to predict functional outcomes after ischemic stroke. They claim the score includes variables easily collected soon after hospitalization. Issues arise when analyzing the sensitivity and positive and negative predictive values in the derivation cohort.1 There are currently several scores available to predict functional outcomes after an ischemic stroke.2,3
