Continuous variables are presented as median (interquartile range) and were compared using the Mann-Whitney U test. Etiology was compared using the Fisher-Freeman-Halton exact test. Favorable outcome: Intensive care unit length of stay ≤10 days without treatment failure (n = 46). Poor outcome: Intensive care unit length of stay >10 days or treatment failure (n = 17). APACHE II: Acute Physiology and Chronic Health Evaluation II; NJ: Nasojejunal; EN: Enteral nutrition; CT: Computed tomography.
