Odds ratios (ORs) with 95% confidence intervals (CIs) were used to present the relative risk of endometriosis.A allele of rs4680 was distinctly correlated with increased susceptibility of endometriosis (OR = 1.450, 95% CI = 1.012-2.076).
This study had the objective of to determine whether the presence of COMT val/met polymorphism (rs4680) increases the risk to endometriosis in infertile patients.
