FAS and posterior cortical atrophy: We performed the multivariate logistic regression analysis and we found that PSA (OR: 1.33; p < 0.01), ATPLy (OR: 3.16; p = 0.049), FAS (OR: 6.58; p < 0.01) and PSMA (OR: 8.05; p < 0.01) were independent predictors of PCa (the model was adjusted for age, total cholesterol and triglycerides).
