The authors of the paper ?Risk of Malnutrition Is an Independent Predictor of Mortality, Length of Hospital Stay, and Hospitalization Costs in Stroke Patients? (Journal of Stroke and Cerebrovascular Diseases [2016]: 799?806) describe a sample of patients admitted to a hospital after suffering a stroke. Each of 537 patients was classified according to a measure of risk of malnutrition (with possible categories low, medium, and high) and whether or not the patient was alive at 6 months following the stroke. The authors concluded that there was an association between survival and the risk of malnutrition. Do you agree? Support your answer with evidence based on that data. For purposes of this exercise, you may assume that the sample of 537 patients is representative of stroke patients.
