GSTP1 and posterior cortical atrophy: For the PCa patients contrast with controls, we detected the remarkable increased PCa risks for people who with dual null genotype of GSTM1 and GSTT1 (OR = 1.4353, 95% CI = 1.0345–1.9913, P = 0.0306, I2 = 55.91%) and people who with GSTT1 null genotype and GSTP1 A131G polymorphism (OR = 1.7335, 95% CI = 1.1067–2.7152, P = 0.0163, I2 = 62.42%).
