Data processing

The study was conducted in accordance with the Declaration of Helsinki (as revised in 2013). The gene expression profiles dataset [433 cases, Workflow Type: HTSeqCounts, corrected by trusted platform module (TPM)] and corresponding clinical data (including survival status and survival time records of 385 BC patients) were downloaded from The Cancer Genome Atlas (TCGA) official website (https://portal.gdc.cancer.gov/) for Bladder Cancer projects (TCGA-BLCA). Gene expression data from expression profiles ({"type":"entrez-geo","attrs":{"text":"GSE13507","term_id":"13507"}}GSE13507, {"type":"entrez-geo","attrs":{"text":"GSE32894","term_id":"32894"}}GSE32894, {"type":"entrez-geo","attrs":{"text":"GSE48075","term_id":"48075"}}GSE48075 and {"type":"entrez-geo","attrs":{"text":"GSE31684","term_id":"31684"}}GSE31684) and corresponding clinical data were obtained from the Gene Expression Omnibus (GEO) datasets (https://www.ncbi.nlm.nih.gov/geo).
