Discovery and Validation of a CT-Based Radiomic Signature for Preoperative Prediction of Early Recurrence in Hypopharyngeal Carcinoma

Figure 4

The prognoses of patients with high recurrent risk was much worse than those of low-risk patients. The risk ratio of recurrence of each individual was calculated by the RadCloud platform. Selection of patients for inclusion into high- or low-risk groups was based on their risk ratio of recurrence, i.e., ≥0.5 for high risk and <0.5 for low risk. Survival analysis between the patients with high and low recurrent risks in the training cohort (a) and in the validation cohort (b), respectively.
