Fig. 3From: Physical activity, sleep disorders, and type of work in the prevention of cognitive function decline in patients with hypertensionThe significance of predictive variables in the decision tree model is a crucial aspect to consider. We included work type, sleep disorders, and physical activity levels in the decision tree model to assess their impact of CFD in hypertensive patients. The figure illustrates the relative importance of each influencing factor in predicting the outcome within the decision tree model. Notably, physical activity level is the root node variable deemed the most critical predictive variableBack to article page
