Development and validation of screening tools for motoric cognitive risk syndrome in community settings

Figure 4 Visualization of the classification tree of decision tree model for identifying motoric cognitive risk. Each node’s text shows the predicted event [non-motoric cognitive risk (MCR)/MCR], the estimated event probability, and the percentage of participants in the training dataset. Blue nodes indicate higher non-MCR prevalence, while pink nodes indicate higher MCR prevalence. The classification tree, constructed using the training dataset, incorporating age, purpose in life, nutritional status, education level, social engagement, depressive symptoms, and physical activity level. MCR: Motoric cognitive risk.
