Figure 4.

Odds ratio (OR) values and coefficients of the selected radiomic features in the delta-radiomics model and the longitudinal fusion radiomic model based on CEe. (a) A total of 9 key features are in the delta-radiomics model, which is the optimal separate radiomic model. (b) The selected 5 features were 2 baseline and 3 delta-radiomics features in the fusion radiomic model of pre-radiomics features and delta-radiomics features. (c) The fusion radiomic model of 1st-radiomics features and delta-radiomics features retains 7 features, 6 from delta-radiomics features and 1 from 1st-radiomics features. (d) A total of 5 features of the fusion radiomic-models of all features based on CEe, and 1 from pre-radiomics features, 1 from 1st- radiomics features, and 3 from delta-radiomics features.
