1. Based on OPTN data, the ability of the model for end-stage liver disease (MELD) to predict short-term pretransplant and posttransplant outcomes was assessed. 2. Concordance with pretransplant mortality was excellent. 3. Concordance with pretransplant mortality was better for candidates listed for a primary transplant. 4. Of the MELD components, there were no statistically significant differences in the effects on pretransplant mortality between candidates listed for a primary or a repeat transplant. 5. Concordance with posttranplant outcomes was poor.
