Study design and clustering dendrogram of the patient samples and clinical traits. (A) Flow diagram of the analysis procedure: data collection, preprocessing, analysis and validation. (B) Clustering was based on the expression data of the differentially expressed genes between KIRC (n = 26) and adjacent normal (n = 26) tissues. The red colour represents the tumour, metastasis and male. Colour intensity is proportional to tumour staging, grading, and age.
