Fig. 4From: Development and validation of a radiomics-based model to predict local progression-free survival after chemo-radiotherapy in patients with esophageal squamous cell cancerKaplan–Meier survival curve of patients with high and low recurrence risk based on Rad-score. A LPFS survival curve of patients in the training cohort: green line represents patients with low risk of local recurrence and red represents patients with high risk of local recurrence. The difference is significant between two groups, p < 0.001. B LPFS survival curve of patients in the validation cohort: green line represents patients with low risk of local recurrence and red line represents patients with high risk of local recurrence. The difference is significant between two groups, p = 0.026Back to article page
