Logistic regression model for predictors of mortality in the high risk group
| Coefficients | Odds ratio | 95% Confidence interval | p value | |
|---|---|---|---|---|
| Age ≥65 yrs | 2.057 | 3.82 | 2.08-29.28 | .002 |
| APACHE II score ≥20 | 1.614 | 5.02 | 1.11-22.70 | .03 |
| SOFA score maximum during ICU stay | 0.224 | 1.25 | 1.03-1.51 | .01 |
| Positive cumulative fluid balance during ICU stay | 1.730 | 5.64 | 1.50-21.14 | .06 |
| No. of categorized risk factors for IAH during ICU stay | 1.200 | 3.32 | 0.94-11.72 | .34 |
| Increased abdominal content during ICU stay | 1.007 | 2.73 | 0.34-21.78 | .08 |
| IAH | 1.409 | 4.09 | 0.83-20.12 | |
| Constant | -9.908 |
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).
