Analysis of expression and clinical correlation for biomarkers. a,b Differential expression of 8 biomarkers in normal and KIRC tissues in the TCGA-KIRC dataset (training set) (a) and the ICGC-RECU-EU dataset (validation set) (b). Note: CTD-2626G11.2 was not annotated in the ICGC test set. c,d Correlation of biomarkers with clinical features in the training set (c) and validation set (d). e-g The expression of biomarkers in KIRC patients under different clinical features (including age, tumor grade, tumor stage and tumor T stage) in the TCGA-KIRC dataset
