Continuous data were reported as means with standard deviations (SDs), medians with interquartile ranges (IQRs), and categorical values were expressed as proportions. Body mass index = BMI, Acute Physiology and Chronic Health Evaluation II = APACHE II; Deyo-Charlson Comorbidity Index = DCCI; intensive care unit = ICU
