Performance of a statistical model to predict stroke outcome in the context of a large, simple, randomized, controlled trial of feeding

Abstract

Background and Purpose-Statistical models to predict the outcome of stroke patients have several uses. Their utility depends on their predictive accuracy in patients other than those on whom they were developed (ie, external validity). We sought to test the external validity of some recently described models in patients enrolled in the FOOD (Feed Or Ordinary Diet) trial: a large randomized trial evaluating feeding policies in patients with stroke.
