Specifically, for each 1-standard deviation (SD) increase in genetically predicted protein levels, the odds ratios (ORs) for PCa were as follows: KDELC2 at 0.89 (95% CI 0.86–0.93), SPINT2 at 1.05 (95% CI 1.03–1.06), TNFRSF10B at 0.74 (95% CI 0.65–0.83), GSTP1 at 0.82 (95% CI 0.74–0.90), and CTSS at 0.91 (95% CI 0.88–0.95). Here, CTSS is linked to posterior cortical atrophy.
