Forest plot about the relationship between the risk of PCa and the MMP2-1306Â T/C gene polymorphism (T-allele vs. C-allele). There were significantly association between MMP2-1306Â T/C gene polymorphism and PCa susceptibility. The squares and horizontal lines correspond to the study specific OR and 95% CI. The area of the squares reflects the weight (inverse of the variance). The diamond represents the summary OR and 95% CI.
