ROC Curve Analysis for the 28-day survival rate prediction model of a random subset (65%) of the data. This model’s performance was internally validated using a random subset of 65% of the data. AUC (area under the curve): The AUC of the ROC curve is 0.851. Sensitivity, which is the model’s ability to correctly identify patients who will survive, is plotted on the y-axis. Specificity, which is the model’s ability to correctly identify patients who will not survive, is plotted on the x-axis. At a given threshold, the model demonstrates a sensitivity of 0.704 with a 95% CI ranging from 0.714 to 0.850.
