Predictors of 1-year major adverse cardiac events using the classification and regression tree model, and risk stratification for patients with acute coronary syndrome. Each predictor was written within line, and each node is based on the data available for each of the predictive variables presented. Each approval rate for each predictor is marked within ovals (intermediate node) or squares (terminal node). WBC, white blood cell; MPV, mean platelet volume; MACEs, major adverse cardiovascular events.
