KLK3 and posterior cortical atrophy: Multivariable logistic regression analysis showed that a family history of PCa (p < 0.0001), African Caribbean ancestry (p = 0.005), PSA density (p = 0.002), prior negative biopsy (p = 0.063), and age at biopsy (p = 0.157) were associated with csPCa presence (Table 2), and, therefore, included in the final ‘PROBA RC’.
