DLRN construction and performance evaluation. (a) is a nomogram for individual prediction of MDM risk combined with the DLRS and independent clinico-radiological features; (b) and (c) are the calibration curves of the DLRN in the training and external validation cohort, respectively; (d) are the decision curves of the DLRN, DLRS, RS, and clinical models of the external validation cohort. DLRN, deep learning radiomics nomogram; DLRS, deep learning radiomics signature; RS, radiomics signature; MDM, metachronous distant metastasis
