Evaluation of the meiosis related prognosis model in TCGA-LUAD and GSE31210. A Survival status and risk scores in TCGA and GSE31210. B PCA analysis of grouped samples in TCGA and GSE31210. C tSNE analysis of grouped samples in TCGA and GSE31210. D The KM curve showed longer OS in the low-risk group whether it was TCGA or GSE31210. E Unsupervised clustering of the 7 candidate genes using the tumor stage, smoking history, gender and risk score as patient annotations in TCGA and GSE31210. F Nomogram based on the 7 meiosis related genes quantitatively predicted the survival of patients with LUAD in TCGA and GSE31210. G Calibration plot for internal validation of the nomogram in TCGA and GSE31210. H AUC values of time-dependent ROC curves verified the predictive accuracy of the risk score in TCGA and GSE31210
