Consequently, the pooled data indicated a certain association between MMP2-1306C/T polymorphism with 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) (Figure 2). Here, MMP2 is linked to posterior cortical atrophy.
