  1. Numbers in brackets are percentages for qualitative variables
  2. Non-normal quantitative variables are expressed as median and interquartile range and compared using Wilcoxon-Test
  3. Normal quantitative variables are expressed as mean ± standard deviation and compared using student test
  4. Bold value are variables included in the propensity matched analysis
  5. CT computerized tomography, NOMI nonocclusive mesenteric ischemia, ASAT aspartate aminotransferase, PaCO2 arterial blood carbon dioxide tension, PaO2 arterial blood oxygen tension, SD standard deviation, PT prothrombin rate, SMD Standard mean deviation
