aChi-square test with Yates' correction; bMann-Whitney U test; cFisher's exact test; dp value was not calculated as the expected frequency was <5 in more than 25% of the cells. BMI, body mass index; APACHE, Acute Physiology and Chronic Health Evaluation; IAP, intra-abdominal pressure; APP, abdominal perfusion pressure; IAH, intra-abdominal hypertension; ICU, intensive care unit.
