- Multivariate logistic regression including 218 complete observations
- Hosmer–Lemeshow p value 0.6
- SAPS II and ICU length of stay were included as continuous variables
- SAPS II was not transformed
- ICU length of stay was included using the following equation x
2 − 1.96 where x = (los)/10
- Covariates were included as continuous variables in the multivariable model
- Presented odds ratios were calculated for the reference indicated in the table
