Fig. 1From: Identification of an immune signature predicting prognosis risk of patients in lung adenocarcinomaThe workflow of construction and validation of the immune signature. The signature consisted of 30 immune related genes in LUAD which was constructed and validated using expression data from the TCGA database (training dataset) and the GEO database (four testing datasets).
