MMP2 and posterior cortical atrophy: There was low heterogeneity regarding the associations of MMP-2 rs243865 (allelic model, I2 = 0.0%, p = 0.837; dominant model, I2 = 0.0%, p = 0.864; recessive model, I2 = 0.9%, p = 0.944) in Asians with LC risk, MMP-2 rs243865 (dominant model, I2 = 7.1%, p = 0.371) in all populations with PCa risk, and MMP-2 rs243865 (allelic model, I2 = 0.0%, p = 0.405; dominant model, I2 = 0.0%, p = 0.696) in Asians with PCa risk.
