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