Fig. 2From: A novel 4-gene signature for overall survival prediction in lung adenocarcinoma patients with lymph node metastasisIdentification of prognostic genes in LNM-positive patients. a Volcano plot showing DEGs in LNM + samples. b Clustering dendrogram of genome-wide genes in LNM + samples. c Correlation between modules and traits. Absolute values of correlation coefficients between LNM-status and modules greater than 0.15 were considered as LNM-related modules. d Five hundred seventy-five overlapping candidates in the intersection of two sets. e LASSO Cox analysis identified 4 genes most correlated with overall survival in the training set. f Cox coefficients distribution of the gene signatureBack to article page
