Logistic Regression Model for In-Hospital Mortality
| Characteristic | Odds Ratio | 95% Confidence Interval |
p-value |
|---|---|---|---|
| Age (years) | 1.020 | 1.002–1.038 | 0.028 |
| APACHE II Score | 1.075 | 1.04–1.111 | <0.001 |
| On Hemodialysis | 0.215 | 0.025–1.838 | 0.16 |
| Chronic Liver Disease | 3.824 | 1.703–8.587 | 0.001 |
| Free Hemoglobin Level (mg/dl) | 1.078 | 1.012–1.149 | 0.020 |
The odds ratio for APACHE II score is for every one point above a score of seven. The odds ratio for Cell-free hemoglobin Concentration is for an increment of every 10 mg/dl above 0 mg/dl. The Hosmer and Lemeshow goodness-of-fit statistic for this model is 0.605.
