Continuous variables were analyzed by Student’s t-test or Mann-Whitney U test, and categorical data by Chi-square test.
bICU: intensive care unit; APACHE II: Acute Physiology and Chronic Health Evaluation II; SOFA: Sequential Organ Failure Assessment; and SAPS II: Simplified Acute Physiology Score II.
cVariables are expressed as mean (standard deviation) and categorical data are expressed as number (percentage).
