Screening path of the least absolute shrinkage and selection operator (LASSO) regression model: (A) IAT model, (B) IPAT 3Â mm model, (C) IPAT 5Â mm model. Penalty parameter (log lambda) in the LASSO regression model: (D) IAT model, (E) IPAT 3Â mm model, (F) IPAT 5Â mm model. Retained radiomics features and corresponding coefficients of different models after dimensionality reduction by LASSO regression: (G) IAT model, (H) IPAT 3Â mm model, (I) IPAT 5Â mm model
