MMP2 and posterior cortical atrophy: Overall, no statistically significant association was observed in MMP2-1306C/T polymorphism with any of the Gleason grading of PCa (T vs C: OR = 1.23, 95% CI = 0.85-1.78, P = 0.264; TT vs CC: OR = 1.88, 95% CI = 0.74-4.80, P = 0.185; TT vs CT: OR = 1.57, 95% CI = 0.60-4.11, P = 0.355; CT+TT vs CC: OR = 1.19, 95% CI = 0.75-1.87, P = 0.461; TT vs CC+CT: OR = 1.77, 95% CI = 0.72-4.35, P = 0.216; respectively).
