MMP2 and posterior cortical atrophy: Consequently, our evidence indicates a certain association between MMP2-1306C/T polymorphism and PCa risk among overall population (T vs C: OR = 1.12, 95% CI = 1.00-1.24, P = 0.040; TT+CT vs CC: OR = 1.16, 95% CI = 1.02-1.32, P = 0.026; respectively), as well as the subgroups of Asian population (T vs C: OR=1.48, 95% CI=1.13-1.94, P=0.004; TT+CT vs CC: OR = 1.66, 95% CI = 1.21-2.28, P = 0.002; respectively) and PCR-RFLP genotyped method (T vs C: OR = 1.58, 95% CI = 1.19-2.10, P = 0.001; TT+CT vs CC: OR = 1.71, 95% CI = 1.23-2.38, P = 0.001; respectively).
