  Fig. 1. Comparison of score distribution and association with ICU mortality. a Distribution of total scores for SOFA-1 and SOFA-2 at ICU admission. b ICU mortality rates (%) stratified by total score points for SOFA-1 and SOFA-2. c Cumulative ICU mortality curves for SOFA-1 and SOFA-2, illustrating the increasing risk of death with higher scores

  Fig. 2. Patient reclassification and predictive performance for mortality. a Heatmap illustrating patient reclassification and associated ICU mortality. Each cell represents patients with a specific combination of SOFA-1 (x-axis) and SOFA-2 (y-axis) scores. In the score distribution matrix, the percentage in each cell represents the proportion of the total patient population. In the mortality matrix, the percentage indicates the ICU mortality rate. b Receiver operating characteristic (ROC) curves for SOFA-1 and SOFA-2 in predicting ICU mortality. c ROC curves for SOFA-1 and SOFA-2 in predicting in-hospital mortality
