Figure 3 Predicted and observed rates of in-hospital mortality in 4 groups divided into 4 quartiles according to their scores using the predictive formula.The gap between the predicted and observed values was small enough that prediction of in-hospital mortality for either group was possible, with sufficient calibration of the model. Microsoft® PowerPoint® for Microsoft 365 MSO (version 2208 build 16.0.15601.20148) was used to create this figure.
