Construction of the prognostic signature.
Notes: (A and B) The prognostic signature constructed by the minimum criterion of LASSO Cox regression algorithm. (C) The Kaplan-Meier survival analysis for high- and low-risk groups. (D) ROC curve was applied to assess the predictive efficiency of the signature. (E–G) Risk scores in different groups regarding survival status, histological type and M stage. *P<0.05, **P<0.01.
