Risk model construction in TCGA cohort. (a) Univariate Cox regression analysis identified 12 necroptosis-related genes correlated with OS. (b) Principal component analysis (PCA) for PC patients according to the risk score. (c) Comparing risk score level between low- and high-risk groups. (d) Survival status for each PC patient. (e) Heatmap exhibiting the expression of the 3 identified necroptosis-related genes expression in different groups. (f) K-M survival analysis based on risk group. (g) ROC curves evaluate the sensitivity and specificity of 1-year survival prediction.
