Machine learning model for predicting hospital-acquired functional decline in older patients with postoperative cardiovascular surgery

Figure 1 SHapley Additive exPlanations analysis of best-performing models. SHapley Additive exPlanations values were calculated for the best-performing models to investigate the effects of individual variables on predictions. The analysis demonstrates how each variable contributes to the model’s predictions for hospital-acquired functional decline. HAFD: Hospital-acquired functional decline.
