Figure 2

Receiver operating characteristic (ROC) curves associated with the area under the curves depicted in Table 3. ROC's are displayed for the scoring systems measured at a single time point (APACHE-II(), SAPS-II(), MPI() compared to the reference line ()) and for sequential scoring systems (MODS(), SOFA(), APS() compared to the reference line ()) measured at day 1 and at day 2.
