Comparison of the diagnostic efficacies of the Fast LN Scoring System and CT/MRI in predicting LN metastasis. A The gene expression heatmap of RT-qPCR validation of the external set. B–F The performance metrics, ROC curve, lift chart, cumulative gain chart and decision curve of CT/MRI imaging and prediction model. G Relationship between risk score and lymph node status. H Association of risk scores with CT/MR Diagnosis of lymph node status. PPV: Positive Predictive Value; NPV: Negative Predictive Value; F1: F1 score; AUC: area under roc curve. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001
