Estimating survival benefit of adjuvant therapy based on a Bayesian network prediction model in curatively resected advanced gallbladder adenocarcinoma

Figure 2 Bayesian network model for advanced gallbladder adenocarcinoma patients after radical resection and the receiver operating characteristic curve for survival time ≤ 9 mo of the bayesian network model. “?” means that the variable has not available values, and we use Structural Expectation-maximization algorithm to imput the not available values in the dataset. Blue lines represent the relationship between the attribute variable and the target variable. Black lines represent the relationship between the attribute variables.
