Fig. 4.

Construction of the transfer risk model associated with NETs. A shows the alluvial plot of NETs grouped in groups with different NETs subtypes, NRGMS and metastasis status. B shows the expression of NETs in the high and low-risk groups (*P < 0.05; ** P < 0.01; *** P < 0.001). C, D shows Kaplan–Meier metastasis curves for OS patients stratified according to risk score in the training and validation cohorts. E–G shows time-dependent ROC analysis of 1-year, 3-year, and 5-year OS prediction for OS patients in the total cohort, training cohort, and validation cohort
