Conversely, the presence of CD25 on unswitched memory cells (OR = 0.9585, 95% CI = 0.9332 to 0.9846, p = 0.0019) and CD24 on unswitched memory cells (OR = 0.9710, 95% CI = 0.9465 to 0.9962, p = 0.0243) was associated with a decreased risk of PCa. This evidence concerns the gene CD24 and posterior cortical atrophy.
