LASSO coefficients of radiomic features. a The LASSO coefficient profiles of the 283 radiomics features. A vertical line was generated at the log (λ) value by using tenfold cross-validation, where the optimal λ value resulted in 18 radiomics features. The optimal λ value of 0.00057 was selected. The X-axis on the top indicates the number of nonzero coefficient features in the model. b The black vertical line was drawn at the value selected using tenfold cross-validation in (a). The X-axis on the top indicates the number of nonzero coefficient features in the model. c Histogram of the Radscore: the Y-axis indicates the selected 18 radiomic features, and the X-axis represents the coefficient of the radiomic features.
