  1. Backward conditional logistic regression based on data in Table 2. Variables for the model were chosen based on clinical usefulness and statistical significance. Receiver operator characteristics curve was plotted to convert continuous variables to dichotomous. Other variables that were included in model: APP < 50 mmHg*, cumulative excess fluid balance > 10,000 ml.
  2. *Most divergent value within 24 h from laparostomy for OA group and within entire follow-up period for matched controls
  3. †IAP > 20 mmHg and new or worsening of existing organ failure
  4. CI, confidence interval; IAP, intra-abdominal pressure; OR, odds ratio; SD, standard deviation
