Fig. 3From: Development and validation of a radiomics-based model to predict local progression-free survival after chemo-radiotherapy in patients with esophageal squamous cell cancerSelection of radiomic features associated with LPFS using the LASSO COX regression model. A Coefficients profiles of radiomic features. The horizontal axis value is logλ, and the vertical axis value represent the coefficients of radiomic features. B The cross-validation curve. The horizontal axis value is logλ, and the vertical axis value is partial likelihood deviance. C The optimal cutoff of Rad-score. Red lines or red dots represent patients at high risk of local recurrence and green lines or green dots represent patients at low risk of local recurrence. The optimal cutoff value is 0.1411, as shown in the vertical line in the figureBack to article page
