APACHE, Acute Physiologic and Chronic Health Evaluation; ICU, intensive care unit. Comparison of variables by analysis of variance: ^aP < 0.05 compared with good prognosis, ^bP < 0.05 compared with bad prognosis in the long term, ^cP < 0.05 compared with bad prognosis in the short term, ^dP < 0.05 compared with expected hospital death.
