As a registered dietitian working in a neurology intensive care unit, I took interest in the results of the study by Yoo et al1 published in the January 2008 issue of the Archives regarding the effect of undernutrition on clinical outcome in ischemic stroke patients. As an advocate of evidence-based nutrition and medicine, I am concerned by the lack of evidence-based criteria used to diagnose undernutrition in this study.
