The MPS ranged from 1.78-5.20 (median, IQR: 1.8; 0.31-3.0) and the MSA from 3-9 (median; IQR: 2; 0-5). Comparing the median value of the two prognostic scores, both were good predictors of death in this cohort (Table 2) . When the four scores were compared, MPS (AUC 0.77; IC95% 0.64-0.90), MSA (0.84; IC95% 0.70-0.98), SAPS II (0.90; IC95% 0.81-0.99) and WHO score (0.91; IC95%0.82-1.0), based on the area under the ROC curve, the best death predictors were SAPS II and the WHO scores ( Figure 3 ).
