Regression coefficients, odds ratios and 95% CI of odds ratios of variables with independent predictive value of survival at 3 and 12 months*
| Coefficient | OR (95% CI) | |
|---|---|---|
| MELD, model for end-stage liver disease; OR, odds ratio. | ||
| *Both models were validated with the bootstrap method. In the bootstrap validations for both models, the same variables entered the bootstrap-derived models most frequently. In fact, MELD score and serum sodium concentration appeared in 94 and 100% of the analyses for 3-month survival, and in 100 and 99% of the analyses for 12-month survival, respectively. Moreover, estimated models using only MELD score and serum sodium concentration as independent predictors were observed in 76% at 3 months. At 12 months, the mentioned model was estimated in 38% of the bootstrapped samples, and in only 1% of the models these two predictors did not appear simultaneously. | ||
