The expression levels of OMD and PRELP in almost all normal bladder tissues were above the cutoff value (specificity: 83.9% (OMD) and 90.3% (PRELP)), while expression in the vast majority of tumor tissues was below the cutoff (sensitivity: 88.9% (OMD) and 90.5% (PRELP), Table S2). This evidence concerns the gene OMD and neoplasm.
