Figure 6 Nomogram, risk score, and survival analysis using the comprehensive model. A: Nomogram of the integrated clinical-radiological-omics model for predicting 3-year progression-free survival (PFS); The progression status, risk scores, and risk stratification for each patient; B: In the training; C: Validation sets. The Kaplan-Meier survival curves for PFS for patients in the high- and low-risk groups; D: In the training; E: Validation sets. BMI: Body mass index; CI: Confidence interval; PFS: Progression-free survival; HR: Hazard ratio; MRF: Mesorectal fascia; TRG: Tumor regression grade; ypN stage: Pathological N stage after neoadjuvant chemoradiotherapy.
