Predictors of mortality in the group with ≥2 categorized risk factors for IAH (87 patients). APACHE II, Acute Physiology and Chronic Health Evaluation; CI, confidence interval; IAH, intra-abdominal hypertension; ICU, intensive care unit; SOFA, Sequential Organ Failure Assessment. Area under receiver operating characteristic curve = 0.78; Hosmer-Lemeshow goodness-of-fit (x2 = 3.78; p = 0.870).
