Figure 1.

Kaplan-Meier survival analyses were performed according to the radiomics score for patients in the training data set (a) and those in the validation data set. (b) The validation set was stratified into a low-and high-risk group based on a cut-off value determined in the training data set. A significant association of the radiomics score with DFS was shown in the training data set, which was then confirmed in the validation data set.
