A significant difference between PCa and BPH was observed only in the UNB fraction, in which the levels of non- or otherwise-glycosylated forms of SPARC were significantly higher in the PCa group (PCA log2H/L = 2.58, BPH log2H/L = 1.58, p = 0.0019). This evidence concerns the gene SPARC and posterior cortical atrophy.
