The area under the receiver operating characteristic curve for the MELD score was 0.612 [+ or -] 0.086 which was significantly lower than that for the [LHL.sub.15] ratio (0.800 [+ or -] 0.063, P <0.001; Figure 5), suggesting that the [LHL.sub.15] ratio was able to predict subsequent mortality more accurately than the MELD score.
