- *Predictors include all admission variables in Table 1 that have P < 0.25
- †The cut-off point was calculated on the basis of ROC curve analysis
- ‡All variables having P < 0.05 from univariate analysis were included in multivariate analysis. Backward stepwise regression methods were performed to create the final model, whereby the least nonsignificant variable was removed from the model one at a time, until all remaining variables had P < 0.05
