Figure 2. Identified DEGs of included datasets.

DEGs between BC samples and normal bladder tissue samples were identified with the cut-off criteria of fold change ≥ 2.0 and P<0.01. The up-regulated DEGs were 425 in GSE7476, 182 in GSE13507, 2008 in GSE40355, 211 in GSE52519 and 1470 in GSE65635. The down-regulated DEGs were 1233 in GSE7476, 634 in GSE13507, 2510 in GSE40355, 315 in GSE52519 and 1761 in GSE65635.
