KLK3 and posterior cortical atrophy: Under the random effects model, the pooled odd ratios for the following were also observed: significant correlation of PSA and PCa risk (<10ng/ml; OR = 5.52, 95% Cl = 2.07–14.70, p = 0.0006; > 10ng/ml; OR = 27.62, 95% Cl = 3.56–213.96, p = 0.0015) for cases when compared to control individuals.
