  1. Calculations of ICU LOS and length of open abdomen were performed excluding deceased patients from each group. Grading of IAH of each group was assessed after surgical decompression.
  2. Data are expressed as mean (SD) and median (IQR 25th to 75th). Percent data are referred to the total population of each group. Statistical analysis: two-tailed Mann-Whitney test and two-tailed Fisher's exact test. *P < 0.05.
  3. APACHE = Acute Physiology And Chronic Health Evaluation; BMI = body mass index; IAH = intraabdominal hypertension; ICU = intensive care unit; IQR = interquartile range; LOS = length of stay; MV = mechanical ventilation; SAPS = Simplified Acute Physiology Score; SD = standard deviation; VAC = vacuum-assisted closure.
