Logistic regression model for predictors of development of IAH in the high risk group
| Coefficients | Odds ratio | 95% confidence interval | p value | |
|---|---|---|---|---|
| Age ≥65 years | 0.780 | 2.18 | 0.66-7.15 | .19 |
| Body mass index ≥30, kg/m2 | 2.312 | 10.09 | 1.97-51.58 | .005 |
| SOFA score at admission | 0.153 | 1.16 | 1.00-1.35 | .04 |
| Number of categorized risk factors for IAH during ICU stay | 0.840 | 2.31 | 1.09-4.88 | .02 |
| Constant | -3.408 |
Predictors of development of IAH in the group with ≥2 categorized risk factors for IAH (87 patients). CI, confidence interval; SOFA, Sequential Organ Failure Assessment; IAH, intra-abdominal hypertension; ICU, intensive care unit. Area under receiver operating characteristic curve = 0.80; Hosmer-Lemeshow goodness-of-fit (x2 = 4.22; p = 0.835).
