External validation of the complement-related gene signature. A–G Kaplan–Meier curves of overall survival between the low and high risk groups based on the median risk scores or the optimal cut off values in GSE13213, GSE19188, GSE30219, GSE31210, GSE41271, GSE50081, and CHCAMS cohorts. H Prognostic effects of each signature gene in TCGA-LUAD. I Prognostic effects of each signature gene in CHCAMS cohort. J Assessment of the abundance of infiltrated immune cells between the low and high risk groups in TCGA-LUAD. ^***P < 0.001. K Comparison of Estimation of STromal and Immune Cells in MAlignant Tumours using Expression Data scores between low and high risk groups in TCGA-LUAD. ^**P < 0.01.
